Bitwise operators in java with example

Core java Interview Questions

• 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) {
10.  
11.   int x=2;
12.  
13.   System.out.println(~x);
14.         
15.   int y= 3;
16.  
17.   System.out.println(~y);
18.         
19.   int z= 4;
20.         
21.   System.out.println(~z);
22.  
23.     }
24.  
25. }

Output:

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

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. 
   
9.    int x=1;
10.    int y=2;
11.         
12.   System.out.println(x&y);
13.         
14.   int i=2;
15.   int j=3;
16.         
17.  System.out.println(i&j);
18.         
19.  System.out.println(4&5);
20.  
21. }
22.  
23. }

Output:

1. 0
2. 2
3. 4

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. 
   
9.    int x=1;
10.    int y=2;
11.         
12.   System.out.println(x|y);
13.         
14.   int i=2;
15.   int j=3;
16.         
17.  System.out.println(i|j);
18.         
19.  System.out.println(4|5);
20.  
21. }
22.  
23. }

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. 
   
9.    int x=1;
10.    int y=2;
11.         
12.   System.out.println(x^y);
13.         
14.   int i=2;
15.   int j=3;
16.         
17.  System.out.println(i^j);
18.         
19.  System.out.println(4^5);
20.  
21. }
22.  
23. }

Output:

1. 3
2. 1
3. 1
