Long class rotateLeft() method

  • rotateLeft() method is available in java.lang package.
  • rotateLeft() method is used to returns the value generated by rotating the binary 2's complement denotation of the given argument (value) left by the given number of bits.
  • rotateLeft() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.
  • rotateLeft() method does not throw an exception at the time of rotating or shifting of bits.

Syntax:

    public static long rotateLeft(long value, int rotation);

Parameter(s):

  • long value – represents the long value to be parsed.
  • int rotation – represents the distance of rotation.

Return value:

The return type of this method is long, it returns a long value generated by rotating the 2's complement binary of the given long value left by the given number of bits.

Example:

// Java program to demonstrate the example 
// of rotateLeft(long value, int rotation) method of Long class

public class RotateLeftOfLongClass {
    public static void main(String[] args) {
        long value = 3;
        int rotation = 1;

        // Iterates till the value of rotation reaches
        while (rotation < 4) {
            // It return the value generated by rotating the 
            // 2's complement of the given argument (value) left
            // by given number of bits
            value = Long.rotateLeft(value, 3);
            System.out.println("value: " + value);
            ++rotation;
        }
    }
}

Output

value: 24
value: 192
value: 1536
