UUID getMostSignificantBits() Method in Java with Examples
The UUIDs are 128-bit values. The getMostSignificantBits() Method of UUID class in Java is used to get the most significant 64 bits of this UUID.
Syntax:
public long getMostSignificantBits()
Parameters: The method does not take any parameters.
Return Value: The method returns an integer value which is the most significant 64 bit of this 128 valued UUID.
Below programs illustrate the working of getMostSignificantBits() method:
Program 1:
// Java code to illustrate// getMostSignificantBits() 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 most significant 64 bit System.out.println("The most significant 64 bit: " + UUID_1 .getMostSignificantBits()); }} |
Output:
UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The value is: 5737 The most significant 64 bit: 6404303215985955288
Program 2:
// Java code to illustrate// getMostSignificantBits() 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 most significant 64 bit System.out.println("The most significant 64 bit: " + UUID_1.getMostSignificantBits()); }} |
Output:
UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The value is: 5737 The most significant 64 bit: 6404303215985955288
