The node() method of UUID class in Java is generally used to get the node value associated with this UUID.
Syntax:
public long node()
Parameters: This method does not take any parameter.
Return Value: This method returns an long value which is the node value associated with this UUID.
Exception: This method throws UnsupportedOperationException If this UUID is not a version 1 UUID
Below programs illustrate the working of node() method:
Program 1:
// Java code to illustrate node() 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 node value System.out.println( "The node value is: " + UUID_1.node()); } } |
UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The node value is: 8796630719078
Program 2:
// Java code to illustrate node() 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 node Value System.out.println( "The node value is: " + UUID_1.node()); } } |
UUID: 5fc03087-d265-11e7-b8c6-83e29cd24f4c The node value is: 145009316876108
