The toString() method of UUID class in Java is generally used to get the string representation of this UUID.
Syntax:
public String toString()
Parameters: This method does not take any parameter.
Return Value: This method returns a String value which is the string representation of this UUID.
Below programs illustrate the working of toString() method:
Program 1:
// Java code to illustrate toString() 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 string representation
System.out.println( "The string representation is: "
+ UUID_1.toString());
}
} |
Output:
UUID: 58e0a7d7-eebc-11d8-9669-0800200c9a66 The string representation is: 58e0a7d7-eebc-11d8-9669-0800200c9a66
Program 2:
// Java code to illustrate toString() 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 toString Value
System.out.println( "The string representation is: "
+ UUID_1.toString());
}

Output:
UUID: 5fc03087-d265-11e7-b8c6-83e29cd24f4c The string representation is: 5fc03087-d265-11e7-b8c6-83e29cd24f4c
