Firstly, you need to import the following package for Calendar class in Javaimport java.util.Calendar;Create a Calendar object and display the current date and timeCalendar calendar = Calendar.getInstance(); System.out.println("Current Date and Time = " + calendar.getTime());Now, let us subtract 1 year using the calendar.add() method and Calendar.YEAR constant. Set a negative value since we are decrementing here −calendar.add(Calendar.YEAR, -1);The following is an exampleExample Live Demoimport java.util.Calendar; public class Demo {    public static void main(String[] args) {       Calendar calendar = Calendar.getInstance();       System.out.println("Current Date = " + calendar.getTime());       // Subtract 1 year from the ...
