Java Calendar: Subtracting Days from a Date

Subtracting a specified number of days from a date can be accomplished with Java's Calendar class. While there's no dedicated function for this purpose, the add() method offers a flexible solution.

Solution:

To subtract "X" days from a date, utilize the following approach:

Calendar calendar = Calendar.getInstance(); // Default to current date and time
calendar.add(Calendar.DAY_OF_MONTH, -X); // Subtract "X" days

This operation modifies the calendar object directly, adjusting its date field by subtracting the specified number of days. The result is a date that is "X" days earlier than the original.
