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
