Every UUID has a variant number describing the generation of this UUID. The variant() method of UUID class in Java is generally used to get variant number associated with this UUID.
Syntax:
public int variant()
Parameters: This method does not take any parameter.
Return Value: This method returns a int value which is the variant number associated with this UUID.
Below programs illustrate the working of variant() method:
Program 1:
// Java code to illustrate variant() 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 variant number System.out.println("The variant number is: " + UUID_1.variant()); }} |
Output:
UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The variant number is: 2
Program 2:
// Java code to illustrate variant() method import java.util.*; public class UUID_Demo { public static void main(String[] args) { // Creating two UUIDs UUID UUID_1 = UUID .fromString( "5fc03087-d265-11e7-b8c6-83e29cd24f4c"); // Displaying the UUID System.out.println("UUID: " + UUID_1); // Displaying the variant Value System.out.println("The variant number is: " + UUID_1.variant()); }} |
Output:
UUID: 5fc03087-d265-11e7-b8c6-83e29cd24f4c The variant number is: 2
