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

    static boolean b;

        short hand = 42;

            hand++;
        if ( hand > 50 );     /* Line 9 */
        else if ( hand > 40 ) 
        {
            hand += 7;
            hand++;    
        }
        else
            --hand;
        System.out.println(hand);
    }
}

    } 
}

1. Assertion checking is typically enabled when a program is deployed.
2. It is never appropriate to write code to handle failure of an assert statement.
3. Assertion checking is typically enabled during program development and testing.
4. Assertion checking can be selectively enabled or disabled on a per-package basis, but not on a per-class basis.
5. Assertion checking can be selectively enabled or disabled on both a per-package basis and a per-class basis.

4. byte z = (byte)100L;
