Java Bitwise Operators
In this chapter you will learn:
Description
Bitwise Operators act upon the individual bits of their operands.
Java bitwise operators can be applied to the integer
types: long, int, short, char, byte.
Bitwise operators List
The following table lists all Java bitwise operators.
| Operator | Result |
|---|---|
| ~ | Bitwise unary NOT |
| & | Bitwise AND |
| | | Bitwise OR |
| ^ | Bitwise exclusive OR |
| >> | Shift right |
| >>> | Shift right zero fill |
| << | Shift left |
| &= | Bitwise AND assignment |
| |= | Bitwise OR assignment |
| ^= | Bitwise exclusive OR assignment |
| >>= | Shift right assignment |
| >>>= | Shift right zero fill assignment |
| <<= | Shift left assignment |
Example
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;/* w w w. jav a 2 s . co m*/
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:
