Bitwise operator assignments combines the assignment with the bitwise operation. The following two statements are equivalent:
a = a >> 4;
a >>= 4;
The following two statements are equivalent:
a = a | b;
a |= b;
The following program demonstrates the bitwise operator assignments:
public class Main {
public static void main(String args[]) {
int a = 1;
int b = 2;
int c = 3;
a |= 2;
b >>= 2;
c <<= 2;
a ^= c;
System.out.println("a = " + a);
System.out.println("b = " + b);
System.out.println("c = " + c);
}
}
The output of this program is shown here:
a = 15
b = 0
c = 12
