LocalDate Class minusMonths() method

• minusMonths() method is available in java.time package.
• minusMonths() method is used to subtract the given months from this LocalDate and return the LocalDate.
• minusMonths() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• minusMonths() method may throw an exception at the time of performing subtraction.
  ArithmeticException: This exception may throw when the calculated result value exceeds the limit.

Syntax:

    public LocalDate minusMonths(long mon_val);

Parameter(s):

• long mon_val – represents the months to be subtracted from this LocalDate.

Return value:

The return type of this method is LocalDate, it returns the LocalDate that holds the value subtracted the given months from this LocalDate.

Example:

// Java program to demonstrate the example 
// of minusMonths(long mon_val) method of LocalDate

import java.time.*;

public class MinusMonthsOfLocalDate {
    public static void main(String args[]) {
        long months = 3;
        // Instantiates two LocalDate
        LocalDate l_da1 = LocalDate.parse("2007-04-04");
        LocalDate l_da2 = LocalDate.of(2008, Month.FEBRUARY, 06);

        // Display l_da1,l_da2 and days
        System.out.println("LocalDate l_da1,l_da2 : ");
        System.out.println("l_da1: " + l_da1);
        System.out.println("l_da2: " + l_da2);
        System.out.println("months to subtract: " + months);

        System.out.println();

        // Here, this method subtracts the given
        // months from this date l_da1 i.e. here
        // we are subtracting 3 months from the 
        // date l_da1
        LocalDate minus_mon = l_da1.minusMonths(months);

        // Display minus_mon
        System.out.println("l_da1.minusMonths(months): " + minus_mon);

        // Here, this method subtracts the given
        // months from this date l_da2 i.e. here
        // we are subtracting 3 months from the
        // date l_da2
        minus_mon = l_da2.minusMonths(months);

        // Display minus_mon
        System.out.println("l_da2.minusMonths(months): " + minus_mon);
    }
}

Output

LocalDate l_da1,l_da2 : 
l_da1: 2007-04-04
l_da2: 2008-02-06
months to subtract: 3

l_da1.minusMonths(months): 2007-01-04
l_da2.minusMonths(months): 2007-11-06
