UUID equals(Object) in Java

equals(Object): This method is available in java.util.UUID class of Java.

Syntax:

boolean java.util.UUID.equals(Object obj)

This method takes one argument. This method compares this object to the specified object. The result is true if and only if the argument is not null, is a UUID object, has the same variant, and contains the same value, bit for bit, as this UUID.

Parameters: One parameter is required for this method.

obj: The object to be compared.

Returns: true if the objects are the same; false otherwise.

Exceptions: NA

Approach

Java

import java.util.UUID;

public class UUIDequals {
    public static void main(String[] args) {

        UUID uuid = 
        UUID.fromString("3800-8cf0-11bd-b23e-10b96e4ef00d");

        UUID obj = 
        UUID.fromString("3800-8cf0-11bd-b23e-10b96e4ef00d");

        System.out.println(uuid.equals(obj));
    }
}

Output:

true
