UUID clockSequence() in Java

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

Syntax:

int java.util.UUID.clockSequence()

This method returns the clock sequence value associated with this UUID.

The 14-bit clock sequence value is constructed from the clock sequence field of this UUID. The clock sequence field is used to guarantee temporal uniqueness in a time-based UUID.

Parameters: NA

Returns: The clock sequence of this UUID.

Throws:

1. UnsupportedOperationException - If this UUID is not a version 1 UUID

Approach

Java

import java.util.UUID;

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

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

        System.out.println(uuid.clockSequence());
    }
}

Output:

12862
