程序 1:

// Java program to demonstrate
// YearMonth.plusMonths() method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        // create YearMonth object
        YearMonth yearmonth
            = YearMonth.parse("2020-05");

        // apply plusMonths() method
        // of YearMonth class
        // Adding 5 months into May 2020
        // will turn it into October 2020
        YearMonth result = yearmonth.plusMonths(5);

        // print results
        System.out.println("Modified YearMonth: "

            = YearMonth.parse("2019-05");

        // apply plusMonths() method
        // of YearMonth class
        // Adding 10 months into it will turn
        // it to 3rd month of next year
        YearMonth result
            = yearmonth.plusMonths(10);
