Output ??

Question

class Example
{
public static void main(String args[ ])
{
int a =3,b =6,c;
System.out.println("a = " +a+"b = " + b);
c = a&b;
System.out.println("a&b = " + c);

c = a | b;
System.out.println("a | b = " + c);

c = a^b;
System.out.println("a^b = " + c);

c = ~b;
System.out.println("~ b= " + c);

c = a<<3;
System.out.println("a<<3 = " + c);

c = b>>2;
System.out.println("b>>2 = " + c);

a = -1
c = a>>>24;
System.out.println("a >>> 24 = " + c);
}

Answer 1

a = 3 00000011
b = 6 00000110
c = a | b; 00000010 = 2 (OR)

a = 3 00000011
b = 6 00000110
c = a | b; 00000111 = 7 (AND)

a = 3 00000011
b = 6 00000110
c = a ^ b; 00000101 = 5 (XOR)

b = 6 00000110
c = ~b; 10000111 = -7
The bitwise complement of 6 (~7) using 2's complement.

a = 3 00000011
c = a<<3; 00011000 = 24

b = 6 00000110
c = b>>2; 00000001 = 1

Not clear about this
a = -1
c = a>>>24;
