Operators and Assignments

What will be the output of the program?

class Bitwise 
{
    public static void main(String [] args) 
    {
        int x = 11 & 9;
        int y = x ^ 3;
        System.out.println( y | 12 );
    }
}

Answer: Option

Explanation:

The & operator produces a 1 bit when both bits are 1. The result of the & operation is 9. The ^ operator produces a 1 bit when exactly one bit is 1; the result of this operation is 10. The | operator produces a 1 bit when at least one bit is 1; the result of this operation is 14.

Agree @Suresh.

I think 15 is the correct answer.

Thanks a lot, @Rashmi.

I didn't understand why 1 or 1 = 0, but you covered that up!

Step 1) 11 & 9.
11 -> 1011.
9 -> 1001.
& -> work like and operator.

1011
1001
----------
1001.

Step 2) X ^ 3.
^ -> XOR operator.
9 -> 1001
3 -> 0011
-------------
1010.

Step 3) 12 | X
x -> OR operator.
1100
1010
---------
1110
1110 -> 14.

1011
1001 & (Bitwise And - Set bit if both bits set).
----
1001 (9)

1001
0011 ^ (Bitwise Exclusive Or - Set bit if ONLY one bit is set).
----
1010 (10)

1010
1100 | (Bitwise Or - Set bit if either bit is set).
----
1110 (14)
