Java is a programming language originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform.
Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture.

Object : An object is a simulation of the real-world entities.
To work with objects, we should be able to identify three key characteristics of objects:

• The object's behavior— what can you do with this object, or what methods can you apply to it?

• The object's state— how does the object react when you apply those methods?

• The object's identity— how is the object distinguished from others that may have the same

behavior and state?

Class :
Classes act as templates for the objects. Classes are structures that holds the member fields and member functions of the object.

Sorting Algorithms

Bubble Sort ==> Click here : Definition and Example in Java

Example in C :

#include <stdio.h>

#include <conio.h>

void main( )

{

int arr[5] = { 25, 17, 31, 13, 2 } ;

int i, j, temp ;

clrscr( ) ;

printf ( "Bubble sort.\n" ) ;

printf ( "\nArray before sorting:\n") ;

for ( i = 0 ; i <= 4 ; i++ )

printf ( "%d\t", arr[i] ) ;

for ( i = 0 ; i <= 3 ; i++ )

{

for ( j = 0 ; j <= 3 - i ; j++ )

{

if ( arr[j] > arr[j + 1] )

{

temp = arr[j] ;

arr[j] = arr[j + 1] ;

arr[j + 1] = temp ;

}

printf ( "\n\nArray after sorting:\n") ;

for ( i = 0 ; i <= 4 ; i++ )

printf ( "%d\t", arr[i] ) ;

getch( ) ;

Microsoft Magic.....!!!!!

MAGIC #1

Found that nobody can create a FOLDER anywhere on the Computer which can be named as "CON". This is something funny and inexplicable? At Microsoft the whole Team, couldn't answer why this happened! TRY IT NOW, IT WILL NOT CREATE A "CON" FOLDER

MAGIC #2

For those of you using Windows, do the following:
1.) Open an empty notepad file
2.) Type "Bush hid the facts" (without the quotes)
3.) Save it as whatever you want.
4.) Close it, and re-open it.
Noticed the weird bug? No one can explain!

MAGIC #3

Again this is something funny and can't be explained?
At Microsoft the whole Team, including Bill Gates, couldn't answer why this happened!
It was discovered by a Brazilian. Try it out yourself?
Open Microsoft Word and type
=rand (200, 99)
And then press ENTER And see the magic?..!

Magic #4

Did you know that a flight number from one of the planes that hit one of the two WTC towers on 9/11 was Q33N. In Notepad / WordPad or MS Word, type that flight number i.e Q33N. Increase the font size to 72. Change the font to Wingdings. ..... u will be amazed by the findings!!

Interview Preparation

Men

Tuck in the shirt and do not roll up the sleeves. Never wear a short-sleeved shirt to an interview or any business purpose. Wearing a short-sleeved shirt will destroy your executive image.

Ties. Optional. But if you do wear one, choose a conservative pattern. Solids, small polka dots, diagonal stripes, small repeating shapes, subtle plaids and paisleys are all acceptable.

Belts. Belts should match your shoes. Those with smaller buckles with squared lines look more professional.

Socks. Black socks are the best, followed by blue or gray, depending on your attire. Never wear white socks! Check your sock length, too--no skin should show when you sit down or cross your legs. Shoes. Black or burgundy leather shoes with laces on them, because tassel loafers are very casual. Other suitable colors are brown, cordovan and navy.

Hair. Keep neat, short and preferably parted on the side. And shave off all those facial hair.

Jewellery. Wear no or little jewellery. The watch and wedding ring are the only acceptable pieces of jewellery to go with the male attire. Thin gold or leather-strapped watches look professional but not digital watches. Also, avoid political or religious insignias, necklaces or bracelets. Definitely no pierced body parts, and cover up your tattoos!

Accessories. As much as possible, use leather briefcases or folders to hold copies of your resume. Use narrow briefcases and avoid plastic folders and plastic ball pens as they are out of place.

Women

Three-piece business suits, blouse and skirt or slacks, and cardigan twin-sets. Sleeveless shirts should be rejected. Short-sleeved blouses are okay when they are tailor-cut or have features such as a sports collar or double breast design to create a business-like look. Skirts can either be long provided it does not create a Cinderella or barn-dance look or short where it falls no shorter than two inches from the knee. Nothing too revealing, please!

Panty-hose or stockings. A must for professional grooming, but nothing with overly fussy patterns. Bring an extra pair, just in case the ones you are wearing run.

Shoes. Closed shoes or pumps with at least 1½-inch heels suggest a more professional look. Dark colors are best.

Hair. Hair longer than shoulder length should be worn up or pulled back. Don't let it fall in front of your face and don't keep trying to fix it during the interview. Avoid large hair ornaments and trendy hairstyles.

Make-up. Be subtle; natural is the key word. Light shades of lip coloring and nail polish are recommended.

Jewellery. Be conservative. Studs of gold, silver or pearls are best. Do away with gaudy fashion jewelers, and those that clank and make noise when one moves.

Accessories. Folders and bags should blend well with the total professional look. Women should match their purse with their shoe colour.

Suggested GD Topics

Is coalition politics here to stay?

The following points could be discussed under this topic:

Nature of coalition politics.Indecisiveness of elections. No particular party is getting the peoples mandate.Advantage of coalition politics in enabling formation of government. Flipside of coalition politics- a party with a handful of seats become powerful.Government falls before tenure. Fresh elections each time. Suggest a way out of this problem, for e.g.: once a party pledges support to a coalition, it will not withdraw its support until it has watched a governments performance for atleast three years...etc The future -will it only have coalitions, emerging political trends...etc...

Does India need a dictator?

The following points could be discussed under this topic:

The current political structure.Drawbacks of it.Bureaucracy, layers in decision making, anarchy. Dictatorship would mean centralised power and faster decision making.But, country run on whims and fancies of an individual.Freedom on individuals could be clamped ..etc.. Present a balanced argument for and against and take up your position on the issue. C h e t a n a S

Is India moving away from a secularist state?

The following points could be discussed under this topic:

Define secularism.Constitution calls our country such a state, but how things have changed over the last 50 years.Spread of nationalism. Division into majority and minority groups-e.g. benefits given to minority groups perceived as a threat by others. Role of non-tolerant neighbors in fuelling fundamentalism. It is a passing phenomenon. We have the national character to overcome this.. Points along these lines can be discussed.

Education in India-or the lack of it.

The following points could be discussed under this topic:

Discuss current education system. Discuss our sociological structure.Poverty which forces kids to drop out to supplement family income.Vicious circle-poverty due to lack of education and vice versa.Suggest solutions to get out of this-for e.g., governments are doing a commendable job with the midday meal schemes but we need more of such efforts. Going down further, why restrict it to government alone? why cant private people, NGOs and other voluntary bodies come forward to do the same? How about tapping corporate funds for such causes .....etc.

What ails Indian sports?

The following points could be discussed under this topic:

A nation of 950 million, we fail to produce great champions barring the occasional Vishwanathan Anand or Geet Sethi. Sports system steeped in bureaucracy. Overriding popularity of cricket leading to neglect in other sports.Traditionally, sports not accorded much importance by us as a career. Need to develop sports from the primary school level- "catch em young". Various incentives to be given to budding sportsmen like academic credits, sports in lieu of a few other subjects etc. Development of sports infrastructure, making it amenable and affordable...etc.....

The Age of Information.

The following points could be discussed under this topic:

Today a plethora of sources to provide information-Newspapers, radio, Television, Internet etc. Information available at the touch of a button. Greater decision making power to the individual. Also easier decision making for the individual. Information is the key to ones success today. One who is more informed forges ahead. The flipside-information overkill. At times deciding is tough due to too much information ...etc.....

Is Philosophy just arm chair theory?

(This is an example of an abstract topic which is thrown up to students once in a while by the examiners)

The following points could be discussed under this topic:

Talk what you know about this topic . Talk of its relevance in day to day life( or irrelevance if you feel so..). Talk of its influence in literature e.g. Influence of Kant on the romantic poets especially Wordsworth or of Bacon, Voltaire et al on the "Enlightenment" period etc. Talk of its influence in politics e.g. Influence of Nietszche on Hitler and subsequent genocide during Nazi regime etc. Talk of ethics and morals and their importance in life. talk of Indian philosophy. the Gita. Discuss whether we use any of these in our lives and their importance in moulding our values...etc...

Success is all about human relations

The following points could be discussed under this topic:

The most important skill for success in to have people on your side. One can get a lot of work done by superiority and hierarchy but one cannot be a leader of men unless one maintains excellent human relations.Its importance not only in professional life but personal life too.Knowledge and expertise does one no good if one cannot maintain proper human relations...etc.

Borderless worlds-Dream or reality?

The following points could be discussed under this topic:

Globalisation of business.Opening up of the various economies. Cross cultural exchanges. More and more people getting an opportunity to work in different lands among different peoples and absorbing a bit of their values and culture.This leads to greater tolerance and understanding of others' problems. The other side-people despite all this have nationalistic and regionalist chauvinism. A world divided into first, second and third worlds. People still talk of "their" economy and not world economy. Europehas shown a step in this direction with EU but its feasibility remains to be seen.So while people clamour for globalisation, they still think only in terms of their national interests...etc...

Quality is a myth in India.

The following points could be discussed under this topic:

The Indian products and manufacturing techniques. Why are we unable to sustain against global competition.Our mindset towards quality. Indian attitude of "chalta hai" which leads to an undemanding customer which in turn lets people get away with substandard products and services. Today competition is forcing our industry to adhere to global standards so we are getting there in terms of quality. Examples of our software industry which is recognised for its ability to meet global standards etc. Since the topic is general, we can extrapolate it to our quality of life-the air , the water , the facilities we have, the infrastructure we have, the services we get and put up with ....etc......

Education and success-Is there a correlation?

The following points could be discussed under this topic:

This is a topic which provides ample scope for dialectics. One can argue for and against it. One of the best examples is Bill Gates who went on to become the richest man in the world despite dropping out of hid education. Closer home we have the example of Dhirubhai Ambani. What a person learns and what he really wants to do has no correlation many a times. A person succeeds only if he likes what he does.The argument for education will be that, in practice, it is your marks and qualifications that opens doors for you. While one can become successful without education, education brings about a richness in one's life. One is able to appreciate many facets of life due to the extended knowledge that education provides. It opens a new window and provides a different perspective towards things, ability to distinguish between ethical and unethical, moral and amoral ....etc. http://www.ChetanaSinterview.com

We don't learn from history, we repeat it

The following points could be discussed under this topic:

Relevance of history. Reminder of our past telling us what to do and what not to do. Still we have numerous examples which have occurred again and again for e.g. Time and again we have had innumerable wars and bloodshed, Hitler made the same mistake as Napoleon and Napoleon in turn the same ones as Alexander and all the three wanted to rule the world, countries making similar mistakes in world war II as they did during world war I ....etc....

But despite this there are also many examples which have not been repeated ( or rather not brought out to the fore as they were not repeated). This could mean we have indeed learnt from history and avoided those mistakes. In fact that has been the purpose of teaching history so as not to repeat them. Today fear of war is directly due to the record history places before us...etc....

Indian villages-our strength or our weakness?

The following points could be discussed under this topic:

A typical Indian villages and its myriad problems. Lack of basic amenities and infrastructure. their contribution to the economy both in goods and services vis-a-vis their urban counterparts. they could be an even bigger drivers of our economy if they are made self reliant by improving infrastructure and reducing the general disparities between cities and villages ...etc...etc

Agrarian Economy in India-boon or bane

The following points could be discussed under this topic:

Speaking for the topic one can argue the following- time and again it has made us self reliant in food. This increases our bargaining power tremendously in the world economy. Internally also food prices can be kept low and this will have a direct bearing on inflation. This would bolster the economy and provide us freedom from world bodies and other nations.

Against the topic-agrarian economy is at the mercy of climatic conditions. A bad summer, monsoon, or winter could bring the nation down. It will have a spiral effect as increased prices will lead to inflation and problems associated with it. World bodies and other nations will dictate terms..etc....

If there were no armies in the world......

The following points could be discussed under this topic:

Wishful thinking indeed! It would be the key element for world peace. There will be no instrument to wage a war. It will also remove fear and distrust among various nations. We wont have a defence budget. This means more funds channelised into other productive areas. Reduced terrorism and very little separatist groups

But the disadvantage could be imposition by one group, anarchy, laissez faire politics, lawlessness..etc..

Do we need a global policeman?

The role of some countries in "disciplining" others. Assuming on itself to decide what is right and what is wrong for the whole world. Bullying others into submission by its sheer economic power. Overriding the brief of world bodies in world politics C he ta naS

Suggest alternatives like more authority to world bodies like UN etc which is more representative of everyone's interests. More assertiveness to be shown by other nations to such policing nations . making more nations self reliant so that we have less of "Big Brother" Syndrome....etc.....

Indian customs-are we in a time warp?

The following points could be discussed under this topic:

Some undesirable practices over a long time. Dowry- prevalent even among the educated class, Sati- recent example of a lady in North India, Child marriages- still prevalent in backward areas etc. Reason on why do we still follow such customs. Traditional subjugation of women-present even in big cities among upper class society. Allied problems due to such customs- intolerance, fundamentalism, exploitation, etchttp://www.ChetanaSinterview.com

Suggest ways out of this like education the masses, indicating the outmodedness and irrelevance of such practices today...etc...

"How green was my valley........".Are we paying the price of nature?

The following points could be discussed under this topic:

As every one tries to be one up on the other in the race for industrialisation, deforestation is taking place on a large scale. This effect is more pronounced in developing countries. It has made a perceptible difference in the last 50 years with rising temperatures. Global warming. Greenhouse effect. Ozone layer depletion. El Nino type effects. Similarly it has affected other living beings-both plant and animals driving many of them to extinction..etc...

But people have realised it now. A lot of NGOs and voluntary bodies are working on it. Infact there is even a Greens party in Germany which has been winning elections using the environmental plank...etc....

Management Education-Is it necessary to succeed in business

The following points could be discussed under this topic:

This is again a topic where we can have for and against arguments. There are many examples of great visionaries and leaders in business who have succeeded without any formal management education. People have simply done it by their will, passion and desire. But management education has also produced many bigwigs. A management education gives a perspective towards analysis and problem solving.It enables one to take decisions in a scientific manner, it enables you to handle the stress and strains of a demanding job...etc...

The role of NGOs in economics and politics

The following points could be discussed under this topic:

NGOs have become very powerful today. They have a major role to play in politics as they swerve peoples opinion. They enjoy a lot of support and goodwill of the people. They can also make or break a business. They protect the interests of the people and represent a collective voice against anything that goes against their interests. Most of the times NGOs are more capable in securing a fair deal for the general good. Also the NGOs have shown that they are in a better position to handle social issues than most governments ...etc...

Internet Terms

Apache : Apache is the most popular Web server software. It enables a computer to host one or more websites that can be accessed over the Internet using a Web browser. The first version of Apache was released in 1995 by the Apache Group.

Applet : This a Java program that can be embedded in a Web page. The difference between a standard Java application and a Java applet is that an applet can't access system resources on the local computer.

ATM: Asynchronous Transfer Mode is a networking technology that transfers data in packets or cells of a fixed size.

Broadband : This refers to high-speed data transmission in which a single cable can carry a large amount of data at once.

Cloud computing : Cloud computing refers to applications and services offered over the Internet. These services are offered from data centers all over the world, which collectively are referred to as the "cloud." The idea of the "cloud" simplifies the many network connections and computer systems involved in online services.

Cookie : A cookie is a small amount of data generated by a website and saved by your web browser. Its purpose is to remember information about you, similar to a preference file created by a software application.

DHCP : Stands for "Dynamic Host Configuration Protocol." A network server uses this protocol to dynamically assign IP addresses to networked computers. The DHCP server waits for a computer to connect to it, then assigns it an IP address from a master list stored on the server.

DNS : Stands for "Domain Name System." The primary purpose of DNS is to keep Web surfers sane. Without DNS, we would have to remember the IP address of every site we wanted to visit, instead of just the domain name.

Firewall : A computer firewall limits the data that can pass through it and protects a networked server or client machine from damage by unauthorized users.

ISDN : Stands for "Integrated Services Digital Network." ISDN is a data transfer technology, created in 1984, that can transfer data significantly faster than a dial-up modem. ISDN enables wide-bandwidth digital transmission over the public telephone network, which means more data can be sent at one time.

P2P : Stands for "Peer to Peer." In a P2P network, the "peers" are computer systems which are connected to each other via the Internet. Files can be shared directly between systems on the network without the need of a central server.

SOAP : Stands for "Simple Object Access Protocol". SOAP is a method of transferring messages, or small amounts of information, over the Internet. SOAP messages are formatted in XML and are typically sent using HTTP (hypertext transfer protocol).

SMTP : Stands for "Simple Mail Transfer Protocol." This is the protocol used for sending e-mail over the Internet.

Software Terms

Algorithm : An algorithm is a set of instructions, sometimes called a procedure or a function, that is used to perform a certain task.

Android :Android is a mobile operating system developed by Google.The Android operating system (OS) is based on the open Linux kernel.

Compiler : A compiler is a software program that compiles program source code files into an executable program. It is included as part of the integrated development environment IDE with most programming software packages

DBMS : Stands for "Database Management System". The DBMS manages incoming data, organizes it, and provides ways for the data to be modified or extracted by users or other programs.

Debugger : A debugger tells the programmer what types of errors it finds and often marks the exact lines of code where the bugs are found. Debuggers also allow programmers to run a program step by step so that they can determine exactly when and why a program crashes. Advanced debuggers provide detailed information about threads and memory being used by the program during each step of execution.

Interpreter : An interpreter is a program that reads and executes code. Interpreters and compilers are similar, since they both recognize and process source code. However, a compiler does not execute the code like and interpreter does.

Middleware : Middleware has two separate but related meanings. One is software that enables two separate programs to interact with each other. Another is a software layer inside a single application that allows different aspects of the program to work together.The most common type of middleware is software that enables two separate programs to communicate and share data.

Operating System : Also known as an "OS," this is the software that communicates with computer hardware on the most basic level. Without an operating system, no software programs can run. The OS is what allocates memory, processes tasks, accesses disks and peripherials, and serves as the user interface.

WYSIWYG : Stands for "What You See Is What You Get," and is pronounced "wihzeewig." WYSIWYG refers to software that accurately represents the final output during the development phase.

Hardware terms
