UUID Class getLeastSignificantBits() method

• getLeastSignificantBits() method is available in java.util package.
• getLeastSignificantBits() method is used to get the least significant 64 bits of these 128 bits.
• getLeastSignificantBits() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• getLeastSignificantBits() method does not throw an exception at the time of getting the least significant bits.

Syntax:

    public long getLeastSignificantBits();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is long, it returns least significant 64 bits of these 128 bits.

Example:

// Java program to demonstrate the example 
// of long getLeastSignificantBits() method of UUID 

import java.util.*;

public class GetLeastSignificantBitsOfUUID {
    public static void main(String[] args) {
        // Instantiate UUID 
        UUID uuid = UUID.fromString("46400000-8cc0-11bd-b43e-10d46e4ef14d");

        // By using getLeastSignificantBits() method
        // is to returns the least significant bits
        long least_sb = uuid.getLeastSignificantBits();

        // Display least_sb
        System.out.println(" uuid.getLeastSignificantBits(): " + least_sb);
    }
}

Output

uuid.getLeastSignificantBits(): -5458907193756683955
