The fromString() method of UUID class in Java is used for the creation of UUID from the standard string representation of the same.
Syntax:
public static UUID fromString(String UUID_name)
Parameters: The method takes one parameter UUID_name which is the string representation of the UUID.
Return Value: The method returns the actual UUID created from the specified string.
Exception: The method throws IllegalArgumentException if an invalid UUID_name is passed.
Below programs illustrate the working of fromString() method:
Program 1:
// Java code to illustrate fromString() method import java.util.*; public class UUID_Demo { public static void main(String[] args) { // Get the string String UUID_name = "5fc03087-d265-11e7-b8c6-83e29cd24f4c"; // Displaying the UUID System.out.println("The specified String is: " + UUID_name); // Creating the UUID UUID UUID_1 = UUID .fromString(UUID_name); // Displaying the UUID System.out.println("The UUID from" + " specified String: " + UUID_1); }} |
Output:
The specified String is: 5fc03087-d265-11e7-b8c6-83e29cd24f4c The UUID from specified String: 5fc03087-d265-11e7-b8c6-83e29cd24f4c
Program 2:
// Java code to illustrate fromString() method import java.util.*; public class UUID_Demo { public static void main(String[] args) { // Get the string String UUID_name = "58e0a7d7-eebc-11d8-9669-0800200c9a66"; // Displaying the UUID System.out.println("The specified String is: " + UUID_name); // Creating the UUID UUID UUID_1 = UUID .fromString(UUID_name); // Displaying the UUID System.out.println("The UUID from" + " specified String: " + UUID_1); }} |
Output:
The specified String is: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The UUID from specified String: 58e0a7d7-eebc-11d8-9669-0800200c9a66
