package com.logicbig.example.localtime;

import java.time.Duration;
import java.time.LocalTime;

public class PlusExample {

    public static void main (String... args) {
        LocalTime d1 = LocalTime.of(22, 30, 50);

        LocalTime d2 = d1.plus(Duration.ofHours(5));
        System.out.println(d2);

        d2 = d1.plus(Duration.ofHours(-5));
        System.out.println(d2);

        d2 = d1.plus(Duration.ofDays(2));
        System.out.println(d2);

    }
}
