Java Bitwise Left Shift

Java Bitwise Left Shift Operator is used to left shift a given value by specified number of bits.

Syntax

The syntax for Bitwise Left Shift operation between x and y operands is

</>
Copy
x << y

The value of x is left shifted by y number of bits.

The operands can be of type int or char. Bitwise Left Shift operator returns a value of type same as that of the given operands.

Examples

In the following example, we take two integer values in x and y, and find the left shift of x by y number of bits.

Main.java

</>
Copy
public class Main {
    public static void main(String[] args) {
        int x = 49;
        int y = 2;
        //Bitwise Left-shift
        int result = x << y;
        System.out.println("Result : " + result);
    }
}

Output

Result : 196
