Decrement a Month using the Calendar Class in Java

Import the following package for Calendar class in Java

import java.util.Calendar;

Firstly, create a Calendar object and display the current date

Calendar calendar = Calendar.getInstance();
System.out.println("Current Date = " + calendar.getTime());

Now, let us decrement the month using the add() method and Calendar.MONTH constant. Set a negative value here since we are decrementing

calendar.add(Calendar.MONTH, -2);

The following is an example

Example

 Live Demo

import java.util.Calendar;
public class Demo {
   public static void main(String[] args) {
      Calendar calendar = Calendar.getInstance();
      System.out.println("Current Date = " + calendar.getTime());
      // Decrementing Month by 2
      calendar.add(Calendar.MONTH, -2);
      System.out.println("Updated Date (-2 Months) = " + calendar.getTime());
   }
}

Output

Current Date = Thu Nov 22 15:57:30 UTC 2018
Updated Date (-2 Months) = Sat Sep 22 15:57:30 UTC 2018
