In this article, we will learn to subtract a year from the current date using Java. We will be using the Calender class of java.util package. Calendar class in Java is an abstract class that provides different methods to convert between a specific instant in time and a set of calendar fields such as HOUR, DAY_OF_MONTH, MONTH, YEAR, and so on. It is also used for manipulating the calender field. Steps to subtract year from current date Following are the steps to subtract year from current date − Import the Calendar class from the java.util package. ... Read More

The Calendar class of java.util package provides a method with the name add(). This method accepts current date and amount of time as parameter values. If the given amount of time is positive, it will add it to the current date, and in the case of negative time, it will subtract it. In this article, we will see a few Java programs to add year to the current date using the Calendar.add() method. Example Scenario: Input 1: current_date = Thu Nov 22 18:19:06 UTC 2018 Input 2: year_to_add = 12 Output: new_date = Thu Nov 22 18:19:06 UTC 2030 ... Read More
