What is Java?
Java is an object oriented programming language developed by Sun Microsystems in early 1990 by developers James Gosling, Mike Sheridan and Patrick Naughton.
In 1991 James Gosling and his friends formed a team called Green Team to further work on this project. The original idea was to develop this programming language for digital devices such as television, set-top box, remote etc. Later this idea was dropped and Java is developed for internet programming.
Why learn Java?
Java Programming language has several features which other programming languages don’t have. Java receives updates regularly which makes it more robust and future proof. Lots of new features are added on every Java release. There are several features of Java, some of them are:
- Platform independent: Java doesn’t depend on the operating system. For example, a program written on Mac OS can run on Windows and vice versa.
- Easy to learn: Syntax is easy and there are lot of tutorials available online including the one which you are currently reading.
- Performance: Java is significantly faster than other traditional interpreted programming languages. Compiled java code which is known as byte code is like a machine code, that allows a faster execution. Java uses Just in Time compiler which can execute the code on demand, this allows to execute only the method that is being called, which makes it faster and efficient.
Hello World Program
public class JavaExample {
public static void main(String[] args){
System.out.println("Hello World");
}
}

Hello Chaitanya,
I am pretty sure that over a period of time you will upload more concepts and tutorials for different technologies, but at the same time I would suggest or better request you to add a frame where you or anybody can post different questions related to particular concept and a person can try writing a code for it. Like a list of programs or something similar to exercises given in Kathy Serra , which on solving can make person better understand the concepts and have hands on programming experience.
Chaitanya Singh says
Seems like a great idea. I would definitely think about it.

Hi Chaitanya
Nice tutorials, Can you put them as a series, So that I don’t have to come back to the homepage to view the second tutorial in the list. It is too much back and forth. Also, the series will act as a roadmap for learning java.
