Below programs illustrate the minusMonths() method of YearMonth in Java:
Program 1:
// Java program to demonstrate
// YearMonth.minusMonths() 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");
// It is May 2020
// apply minusMonths() method
// of YearMonth class
YearMonth result
= yearmonth.minusMonths(2);
// It subtracts 2 months from May 2020
// So it will be March 2020
// print year and month both
System.out.println("Modified YearMonth: "
+ result);
}
}
Output:
Modified YearMonth: 2020-03
Program 2:
// Java program to demonstrate
// YearMonth.minusMonths() method
import java.time.*;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
// create YearMonth object
YearMonth yearmonth
= YearMonth.parse("2019-10");
// apply minusMonths() method
// of YearMonth class
YearMonth result
= yearmonth.minusMonths(10);
// Subtracting 10 months will turn it into
// December of 2018 (previous year)
// print year and month both
System.out.println(
"Modified YearMonth: "
+ result);
}
}
Output:
Modified YearMonth: 2018-12
