UUID version() Method in Java with Examples

Every UUID has a version number describing the generation of this UUID. The version() method of UUID class in Java is generally used to get version number associated with this UUID.

Syntax:

public int version()

Parameters: This method does not take any parameter.

Return Value: This method returns a int value which is the version number associated with this UUID.

Below programs illustrate the working of version() method:

Program 1:

// Java code to illustrate version() 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 version number 
        System.out.println("The version number is: "
                           + UUID_1.version()); 
    } 
} 

Output:

UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66
The version number is: 1

Program 2:

// Java code to illustrate version() 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 version Value 
        System.out.println("The version number is: "
                           + UUID_1.version()); 
    } 
} 

Output:

UUID: 5fc03087-d265-11e7-b8c6-83e29cd24f4c
The version number is: 1
