UUID Class equals() method

• equals() method is available in java.util package.
• equals() method is used to check whether this object equals to the given object or not.
• equals() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• equals() method does not throw an exception at the time of checking the equality of two objects.

Syntax:

    public boolean equals(Object ob);

Parameter(s):

Example:

// Java program to demonstrate the example 
// of boolean equals(Object ob) method of UUID 

import java.util.*;

public class EqualsOfUUID {
    public static void main(String[] args) {
        // Instantiate UUID    
        UUID uuid1 = UUID.fromString("46400000-8cc0-11bd-b43e-10d46e4ef14d");
        UUID uuid2 = UUID.fromString("56500000-8cd0-10bd-b65e-10d46e4ef14d");

        // By using equals() method is
        // to check equality of this object
        // with the given object
        boolean status = uuid1.equals(uuid2);
        System.out.println("uuid1.equals(uuid2): " + status);
