Example:

In the example below, the java.util.UUID.node() method returns the node value of the given UUID.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating an UUID
    UUID uid = UUID.fromString("d81e4f2e-cdf2-10e6-529b-7df92533d1cb");

    //printing the node value of the uuid
    System.out.println("Node Value: " + uid.node());  
  }
}

The output of the above code will be:
