In this article we will see the use of Bitwise Left Shift operator in Java programming language.

Java Program on Bitwise Left Shift Operator

Left shift operator in java: Bitwise Left Shift operator is also called as Signed Left Shift operator which is represented by << symbol. It shifts the bits of a number towards left with specified position.

During shift the left most bit(most significant) is discarded and the right shift bit(least significant) is replaced with 0.

Note:  Unsigned left shift operator (<<<) is not supported in Java.

Syntax:

value<<position

Where

  • value represents the binary value on which shift operation will be performed
  • position refers to the specified position on which left shift will happen by shifting bits towards left with that position

For Example:

Suppose the number is 3 whose binary is 0011

We will perform 1 bit left shift then the value will become 0110 which is 6

Program-1:(1 bit left shift operation)

class Main 
{
  public static void main(String[] args) 
  {
    //number is 3
    int num = 3;
    //performing 1 bit left shift operation 
    int result = num << 1;
    //prints 6
    System.out.println("After left shift operation:"+result);    
  }
}
Output:

After left shift operation:6

Program-2:(2 bit left shift operation)

class Main 
{
  public static void main(String[] args) 
  {
    //number is 2
    int num = 2;
    //performing 2 bit left shift operation 
    int result = num << 2;
    //prints 8
    System.out.println("After left shift operation: "+result);    
  }
}
Output:

After left shift operation: 8
