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
