Bitwise Operator all in one

public class BitwiseOperator {

   public static void main(String args[]) {
      int p = 60;	/* 60 = 0011 1100 */
      int q = 13;	/* 13 = 0000 1101 */
      int c = 0;

      c = p & q;        /* 12 = 0000 1100 */
      System.out.println("p & q = " + c );

      c = p | q;        /* 61 = 0011 1101 */
      System.out.println("p | q = " + c );

      c = p ^ q;        /* 49 = 0011 0001 */
      System.out.println("p ^ q = " + c );

      c = ~p;           /*-61 = 1100 0011 */
      System.out.println("~p = " + c );

      c = p > 2;       /* 15 = 1111 */
      System.out.println("p >> 2  = " + c );

      c = p >>> 2;      /* 15 = 0000 1111 */
      System.out.println("p >>> 2 = " + c );
   }
}

Output

p & q = 12
p | q = 61
p ^ q = 49
~p = -61
p > 2  = 15
p >>> 2 = 15

Bitwise complement operator

If a = 10 then What will be the output of ~ a ?

a = 10 ( here no sign)
a = +10 (no sing means it is positive) a = 0 1010 (in binary Sign and Magnitude) a = 0 1010 (in two’s complement form)

a = 0 1010 (in two’s complement form) b = ~a = 1 0101 ( Here we performed Bitwise Complement operation) Now b = - 5 ( But this is not our Result)

So What Will be the Solution

We have to convert the b = 1 0101 in two’s complement form because here the sign bit is 1 that means it is negative.

b = 1 0101
Now two’s complement of b means (1’s complement 0f  0101 + 1), here no need to consider sign bit.

• 0101 one’s complement result will be 1010
• 1010 +1 = 1011 (two’s complement of b)
• So our final result will be b = 1 1011
• b = 1 1011
• b = - 11

a = -10 ( Here sign exist ) a = 1 1010 (in binary Sign and Magnitude) a = 1 0110 (in two’s complement form)

a = 1 0110 (in two’s complement form) b = ~ a = 0 1001 ( Here we performed Bitwise Complement operation) Now, b = +9 ( Our Result )
