How to Subtract Days from a Date in Java Using Calendar?

Subtracting Days from a Date in Java Using Calendar

In Java, there is no direct function specifically designed to subtract a specified number of days from a date. However, the Calendar class provides a versatile solution to handle this task.

Solution:

To subtract X days from a date using the Java Calendar, follow these steps:

  1. Create an instance of the Calendar class:
Calendar calendar = Calendar.getInstance();
  1. Use the add() method to subtract the specified number of days from the desired calendar field. For days, use the DAY_OF_MONTH field as follows:
calendar.add(Calendar.DAY_OF_MONTH, -X);

In this code, -X represents the number of days to be subtracted.

  1. The add() method modifies the calendar instance in place. The resulting calendar object will now reflect the updated date with the specified days subtracted.

Example:

Assuming you have a date stored in the calendar object, to subtract 5 days from this date, you would write:

calendar.add(Calendar.DAY_OF_MONTH, -5);

This operation modifies the calendar to represent the date that is 5 days prior to the original date.
