Explain about bit-wise operators with an example

 

Bitwise Operator in Java

In Java, an operator is a symbol that performs the specified operations. In this section, we will discuss only the bitwise operator and its types with proper examples.

Types of Bitwise Operator

There are six types of the bitwise operator in Java:

• Bitwise AND
• Bitwise exclusive OR
• Bitwise inclusive OR
• Bitwise Compliment
• Bit Shift Operators

Operators	Symbol	Uses
Bitwise AND	&	op1 & op2
Bitwise exclusive OR	^	op1 ^ op2
Bitwise inclusive OR	|	op1 | op2
Bitwise Compliment	~	~ op
Bitwise left shift	<<	op1 << op2
Bitwise right shift	>>	op1 >> op2
Unsigned Right Shift Operator	>>> op >>>	number of places to shift

Let's explain the bitwise operator in detail.

Bitwise AND (&)

It is a binary operator denoted by the symbol &. It returns 1 if and only if both bits are 1, else returns 0.

Let's use the bitwise AND operator in a Java program.

BitwiseAndExample.java

1. public class BitwiseAndExample   
2. {   
3. public static void main(String[] args)   
4. {   
5. int x = 9, y = 8;   
6. // bitwise and   
7. // 1001 & 1000 = 1000 = 8  
8. System.out.println("x & y = " + (x & y));   
9. }  
10. }  

Output

x & y = 8

Bitwise exclusive OR (^)

It is a binary operator denoted by the symbol ^ (pronounced as caret). It returns 0 if both bits are the same, else returns 1.

Let's use the bitwise exclusive OR operator in a Java program.

BitwiseXorExample.java

1. public class BitwiseXorExample   
2. {   
3. public static void main(String[] args)   
4. {   
5. int x = 9, y = 8;   
6. // bitwise XOR   
7. // 1001 ^ 1000 = 0001 = 1  
8. System.out.println("x ^ y = " + (x ^ y));   
9. }  
10. }  

Output

x ^ y = 1
