Bitwise Operators in Java

Java bitwise operators are used to manipulating bits of a number. We can use bitwise operators with any integral datatype like byte, short, int, long.

Types of Java Bitwise Operators

There are the following types of bitwise operators are used in Java,

1. Java Bitwise AND (&)
2. Java Bitwise OR (|)
3. Java Bitwise XOR (^)
4. Java Bitwise Complement (~)
5. Java Bitwise Left Shift (<<)
6. Java Bitwise Right Shift (>>)
7. Java Bitwise Unsigned Right Shift Operator (>>>)

Java Bitwise Operators: Tabular Representation

Operator	Symbol	Example
Bitwise AND	&	Operand1 & Operand2
Bitwise OR	|	Operand1 | Operand2
Bitwise XOR	^	Operand1 ^ Operand2
Bitwise Complement	~	~Operand1
Bitwise Left Shift	<<	Operand1 << Operand2
Bitwise Right Shift	>>	Operand1 >> Operand2
Bitwise Unsigned Right Shift Operator	>>>	Operand1 >>> Operand2

1. Java Bitwise AND Operator (&)

This is a binary operator, which is denoted by symbol '&'. It performs bit by bit AND operation on given number, if both bits are 1, then output will be 1, otherwise it will 0.

Operand1	Operand2	Operand1 & Operand2
1	1	1
1	0	0
0	1	0
0	0	0

Example of Java Bitwise AND Operator

public class Main {
  public static void main(String[] args) {

    int num1 = 5; // 0101
    int num2 = 7; // 0111

    int res = 0;

    res = num1 & num2;

    /*
        0101
        0111
        ====
        0101  That is 5
    */

    System.out.println("Result: " + res);
  }
}

Output:

Result: 5

2. Java Bitwise OR Operator (|)

This is a binary operator, which is denoted by symbol '|'. It performs bit by bit OR operation on given number, if any bit is 1, then output will be 1, otherwise it will 0.

Operand1	Operand2	Operand1 | Operand2
1	1	1
1	0	1
0	1	1
0	0	0

Example of Java Bitwise OR Operator

public class Main {
  public static void main(String[] args) {

    int num1 = 5; // 0101
    int num2 = 7; // 0111

    int res = 0;

    res = num1 | num2;

    /*
        0101
        0111
        ====
        0111  That is 7
    */

    System.out.println("Result: " + res);
  }
}

Output:

Result: 7

3. Java Bitwise XOR Operator (^)

This is a binary operator, which is denoted by symbol '^'. It performs bit by bit XOR operation on given number, if both bits are different, then output will be 1, otherwise it will 0.

Operand1	Operand2	Operand1 | Operand2
1	1	0
1	0	1
0	1	0
0	0	0

Example of Java Bitwise XOR Operator

public class Main {
  public static void main(String[] args) {

    int num1 = 5; // 0101
    int num2 = 7; // 0111

    int res = 0;

    res = num1 ^ num2;

    /*
        0101
        0111
        ====
        0010  That is 2
    */

    System.out.println("Result: " + res);
  }
}

Output:

Result: 2

4. Java Bitwise Complement Operator (~)

This is a unary operator, which is denoted by symbol '~'. It performs bit by bit 1's complement operation on given number. It inverted the bits.

Operand	~Operand
1	0
0	1

5. Java Bitwise Left Shift Operator (<<)

It is a binary operator, which shifts the number bits to the left in given number. The left-shift operator multiplies the number of specified bits of power of 2 with the given number.

Example of Java Bitwise Left Shift Operator

public class Main {
  public static void main(String[] args) {

    byte num = -5;
    byte res = 0;

    res = (byte)(num << 3);

    /*
        res = -5 * (2*2*2)
        res = -40
    */

    System.out.println("Result: " + res);
  }
}

Output:

Result: -40

6. Java Bitwise Right Shift Operator (>>)

It is a binary operator, which shifts the number bits to the right in given number. The right-shift operator divides the number of specified bits of power of 2 with the given number.

Example of Java Bitwise Right Shift Operator

public class Main {
  public static void main(String[] args) {

    byte num = -64;
    byte res = 0;

    res = (byte)(num >> 3);

    /*
        res = -64 / (2*2*2)
        res = -8
    */

    System.out.println("Result: " + res);
  }
}

Output:

Result: -8

7. Java Bitwise Unsigned Right Shift Operator (>>>)

It is a binary operator, which shifts the number bits to the right in given number. The unsigned right-shift operator divides the unsigned number of specified bits of power of 2 with the given number.

Example of Java Bitwise Unsigned Right Shift Operator

public class Main {
  public static void main(String[] args) {

    byte num = 64;
    byte res = 0;

    res = (byte)(num >>> 3);

    /*
        res = 64 / (2*2*2)
        res = 8
    */

    System.out.println("Result: " + res);
  }
}

Output:

Result: 8
