Bitwise Operators in Java
In this post, you will learn how to work with bitwise operators so that you can use that same knowledge and thus evolve.
- bitwise operators operate one bit at a time and it is important to be aware of what binary code is.
1 |
Real |
0 |
False |
& |
Only true when both numbers correspond to 1 and 1 |
| |
It is only false when both numbers match 0 and 0 |
<< |
Shift bits according to given number to the left |
>> |
Shift bits according to given number to the right |
- then we also have the operators
^and~; - such operators are mostly used in various situations (encryption, data compression, production of hash codes, communication with hardware, games and etc).
package com.caffeinealgorithm.programminginjava;
public class BitwiseOperators {
private int x = 60; // 00111100 < 01111000 < 11110000 | 00111100 > 00011110 > 00001111
private int y = 13; // 00001101
public void Run() {
System.out.printf("Result of operator &: %d\n", x & y); // 12 -> 00001100
System.out.printf("Result of operator |: %d\n", x | y); // 61 -> 00111101
System.out.printf("Result of operator <<: %d\n", x << 2); // 240 -> 11110000
System.out.printf("Result of operator >>: %d", x >> 2); // 15 -> 00001111
}
}
/*
Result of operator &: 12
Result of operator |: 61
Result of operator <<: 240
Result of operator >>: 15
*/
