My first Java program

Type the following code ( or copy and paste ) into a text file and save as "Hello.java".  You have to explicitly give the extension .java and the file name should match the class name you are creating.  Remember it is case sensitive.

Source

import java.util.* ;

public class Hello {
    public static void main( String args[] ) {
        System.out.println( "OOPS! It is a good start!!! ) ;
    }
}

To compile your first program type the following command from the DOS prompt.

javac Hello.java

Hello.class will be created if there is no error.  To run your program type the following command:

java Hello.class

or

java Hello

You will see the message displayed.

Have you enjoyed your first java program.
