Flow Control

Q1:

What will be the output of the program? 
public class If1 
{
    static boolean b;
    public static void main(String [] args) 
    {
        short hand = 42;
        if ( hand < 50 && !b ) /* Line 7 */
            hand++;
        if ( hand > 50 );     /* Line 9 */
        else if ( hand > 40 ) 
        {
            hand += 7;
            hand++;    
        }
        else
            --hand;
        System.out.println(hand);
    }
}

A 41

B 42

C 50

D 51

ANS:A - 41

In Java, boolean instance variables are initialized to false, so the if test on line 7 is true and hand is incremented. Line 9 is legal syntax, a do nothing statement. The else-if is true so hand has 7 added to it and is then incremented.
