What will be the output of the program?

public class Test 
{ 
    public static void main (String[] args) 
    {
        String foo = args[1]; 
        String bar = args[2]; 
        String baz = args[3]; 
        System.out.println('baz = ' + baz); /* Line 8 */
    } 
}

And the command line invocation: > java Test red green blue

ANS:A - baz =

When running the program you entered 3 arguments 'red', 'green' and 'blue'. When dealing with arrays in java you must remember ALL ARRAYS IN JAVA ARE ZERO BASED therefore args[0] becomes 'red', args[1] becomes 'green' and args[2] becomes 'blue'. When the program entcounters line 8 above at runtime it looks for args[3] which has never been created therefore you get an ArrayIndexOutOfBoundsException at runtime.
