Program 1:




// Java program to demonstrate
// YearMonth.plus(TemporalAmount amountToadd) method
  
import java.time.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // create a YearMonth object
        YearMonth thisYearMonth = YearMonth.of(2019, 11);
  
        // print instance
        System.out.println("YearMonth :"
                           + thisYearMonth);
  
        // create temporalAmount object from period class
        // passing temporalAmount to
        // plus() method
        YearMonth value
            = thisYearMonth.plus(
                Period.ofYears(120));
  
        // print result
        System.out.println("Value after addition: "
                           + value);
    }
}
Output:
YearMonth :2019-11

        // create temporalAmount object from period class
        // passing temporalAmount to
        // plus() method
        YearMonth value
