How to write "Hello World" in Java
The first step to getting familiar with a new language is to write a simple “Hello World” program. To create a “Hello World” program in Java, just follow these simple steps:
- Create a file (i.e.,
helloworld.java). - Make sure that the outer class is of the same name as the filename, without extension (i.e., helloworld).
- Now write the main method for the helloworld class.
Code
In the code below, the same steps are followed for the Hello World program.
Remember, every program in Java consists of a main method with the same signature, i.e.,
public static void main(String []args).
class HelloWorld {public static void main( String []args ) {System.out.println( "Hello World!" );}}
