java.time.OffsetTime Class in Java

Read

Practice

Java OffsetTime class is an immutable date-time object that represents a time, often viewed as hour-minute-second offset. OffsetTime class represents a time with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as 18:30:45+08:00, often viewed as an hour-minute-second-offset. This class is immutable and thread-safe, stores all time fields, to a precision of nanoseconds, as well as a zone offset.

Syntax: Class declaration

public final class OffsetTime extends Object   
implements Temporal, TemporalAdjuster, Comparable<OffsetTime>, Serializable

// Java Program to Implement OffsetTime class
// via now() method
 
// Importing required classes
import java.time.OffsetTime;
import java.time.temporal.ChronoField;

    // Main driver method
    public static void main(String[] args)
    {
 
        // Creating an object of class in main() method
        OffsetTime offset = OffsetTime.now();
