UUID getLeastSignificantBits() Method in Java with Examples Last Updated : 27 Dec, 2018 Comments Improve Suggest changes Like Article Like Report The UUIDs are 128-bit values. The getLeastSignificantBits() Method of UUID class in Java is used to get the least significant 64 bits of this UUID. Syntax: public long getLeastSignificantBits() Parameters: The method does not take any parameters. Return Value: The method returns an integer value which is the least significant 64 bit of this 128 valued UUID. Below programs illustrate the working of getLeastSignificantBits() method: Program 1: Java // Java code to illustrate // getLeastSignificantBits() method import java.util.*; public class UUID_Demo { public static void main(String[] args) { // Creating two UUIDs UUID UUID_1 = UUID .fromString( "58e0a7d7-eebc-11d8-9669-0800200c9a66"); // Displaying the UUID System.out.println("UUID: " + UUID_1); // Displaying the value of UUID System.out.println("The value is: " + UUID_1.clockSequence()); // Getting the least significant 64 bit System.out.println("The least significant 64 bit: " + UUID_1 .getLeastSignificantBits()); } } Output: UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The value is: 5737 The least significant 64 bit: -7608541298835023258 Program 2: Java // Java code to illustrate // getLeastSignificantBits() method import java.util.*; public class UUID_Demo { public static void main(String[] args) { // Creating two UUIDs UUID UUID_1 = UUID .fromString( "58e0a7d7-eebc-11d8-9669-0800200c9a66"); // Displaying the UUID System.out.println("UUID: " + UUID_1); // Displaying the value of UUID System.out.println("The value is: " + UUID_1.clockSequence()); // Getting the least significant 64 bit System.out.println("The least significant 64 bit: " + UUID_1.getLeastSignificantBits()); } } Output: UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The value is: 5737 The least significant 64 bit: -7608541298835023258 Comment More infoAdvertise with us Next Article Introduction to Java C chinmoy lenka Follow Improve Article Tags : Misc Java Java - util package Java-Functions Java-UUID +1 More Practice Tags : JavaMisc Similar Reads Java Tutorial Java is a high-level, object-oriented programming language used to build web apps, mobile applications, and enterprise software systems.
