Java "&" operator

In this section you will learn how to use "&" operator in java. Java provide six types of operators: among them one is Bitwise operator which can be applied to integer, long, int char short type. "&" operator comes under type of Bitwise operator in java. Bitwise operator work on bit and perform bit by bit operation.

Java "&" operator.

In this section you will learn how to use "&" operator in java. Java provide six types of operators: among them one is Bitwise operator which can be applied to integer, long,  int char short type. "&" operator comes under type of Bitwise operator in java. Bitwise operator work on bit and perform bit by bit operation.

Example: let us suppose a=10 and b=20, Now in binary format they will be as follows:

a = 0000 1010

b = 0001 0100

a & b = 0000 0000

"&" operator work on bit , so it will produces 1 if both operand will be 1(1&1). But if both bit are 0 or different (0&1) it will produces 0. In more simple word , if both bit are 1 then it will produce 1 but if one of the bit is 0 then it will produce 0. In the above example we can see that the most last bit in 'a' is 0 and the most last bit in 'b' is 0, so it produces 0 only in result that is in c.

Code to display use of "&" operator in Java: A simple example using Bitwise (AND) "&" operator.

public class operators{

	public static void main(String args[])
	{
		int a=10,b=20,c=0; 
                //int a=5,b=6;
		c=a&b; 
		System.out.println("Result of A & b = "+c);
	}
}
 
In the above example, a is 10 that is 0000 1010 and b is 0001 0100  all bit are different so it produces 0 as output. Not a single bit is same that is 1 in both operand either  a or b.

Output:

When you will take the value of a=10 and b=20 then the output will be as follows :

When you will take the value of a=5 and b=6 then the output will be as follows :
