» » Bitwise operators in java with example

  • Bitwise operators in java performs operation on bits 
  • Bitwise operators performs bit by bit operations
  • Bit-wise operators operates on individual bits of operands.



 Bit wise Operators in Java:

  1. ~      : Bit wise unary not
  2. &     : Bit wise And
  3. |       : Bit wise OR
  4. ^      : Bit wise Exclusive OR


 1.Bit wise Unary Not  ~:

  • Bit wise Unary not Inverts the bits.
  • Lets see a java program on bit wise unary not

Java Example program on bit wise unary not operator ~:

  1. package operatorsinjava;
  2. public class BitwiseUnaryNotDemo {
  3.  
  4.     /**
  5.      * @www.instanceofjava.com
  6.      */
  7.     public static void main(String[] args) {
  8.  
  9.   int x=2;
  10.  
  11.   System.out.println(~x);
  12.         
  13.   int y= 3;
  14.  
  15.   System.out.println(~y);
  16.         
  17.   int z= 4;
  18.         
  19.   System.out.println(~z);
  20.  
  21.     }
  22.  
  23. }

Output:


  1. -3
  2. -4
  3. -5

bitwise unary operator in java


2. Bitwise AND operator:

  • Bit wise And returns 1 if both operands position values are 1 otherwise 0.
  • Bitwise operation on two numbers
  • 1 & 2
  • 001
    010
    -----
    000 =0
    -----
  • 2 & 3
  • 010
    011
    -----
    010 =2
    -----
Java Example program on bitwise AND operator &:


  1. package operatorsinjava;
  2. public class BitwiseAndDemo {
  3.  
  4.     /**
  5.      * @www.instanceofjava.com
  6.      */
  7. public static void main(String[] args) {

  8.    int x=1;
  9.    int y=2;
  10.         
  11.   System.out.println(x&y);
  12.         
  13.   int i=2;
  14.   int j=3;
  15.         
  16.  System.out.println(i&j);
  17.         
  18.  System.out.println(4&5);
  19.  
  20. }
  21.  
  22. }

Output:


  1. 0
  2. 2
  3. 4
Bitwise And operator in java Example


3.Bitwise OR operator in Java | :

  • Bit wise OR returns 1 if  any one operands position values are 1 or both 1 s. otherwise 0.
  • 1 |2
  • 001
    010
    -----
    011 =3
    -----
  • 2 | 3
  • 010
    011
    -----
    011 =3
    -----
Java Example program on bitwise OR operator |:

  1. package operatorsinjava;
  2. public class BitwiseORDemo {
  3.  
  4.     /**
  5.      * @www.instanceofjava.com
  6.      */
  7. public static void main(String[] args) {

  8.    int x=1;
  9.    int y=2;
  10.         
  11.   System.out.println(x|y);
  12.         
  13.   int i=2;
  14.   int j=3;
  15.         
  16.  System.out.println(i|j);
  17.         
  18.  System.out.println(4|5);
  19.  
  20. }
  21.  
  22. }

Output:

  1. 3
  2. 3
  3. 5

4.Bit wise Exclusive OR operator in java ^:

  • Bit wise XOR operator returns 1 if any of the operands bits position 1 
  • Java XOR operator returns 0 if both operands position is 1.
  • Lest see java Xor on 1 ^ 2
  • 1 ^ 2
  • 001
    010
    -----
    011 =3
    -----
  • Lest see java xor operation on 2 ^3
  • 2 ^ 3
  • 010
    011
    -----
    001 =1
    -----

Java Example program on bitwise OR operator |:

  1. package operatorsinjava;
  2. public class BitwiseXORDemo {
  3.  
  4.     /**
  5.      * @www.instanceofjava.com
  6.      */
  7. public static void main(String[] args) {

  8.    int x=1;
  9.    int y=2;
  10.         
  11.   System.out.println(x^y);
  12.         
  13.   int i=2;
  14.   int j=3;
  15.         
  16.  System.out.println(i^j);
  17.         
  18.  System.out.println(4^5);
  19.  
  20. }
  21.  
  22. }

Output:

  1. 3
  2. 1
  3. 1
