Modify Date and Time from GregorianCalendar in Java
For GregorianCalendar class, import the following package.
import java.util.GregorianCalendar;
Firstly, let us display the current date and time.
GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance();
System.out.println("Current date: " + cal.getTime());Now, modify the date. Here we are adding two days to the month using the add() method.
cal.add((GregorianCalendar.MONTH), 2);
Example
import java.util.Calendar;
import java.util.GregorianCalendar;
public class Demo {
public static void main(String[] a) {
GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance();
System.out.println("Current date: " + cal.getTime());
cal.add((GregorianCalendar.MONTH), 2);
System.out.println("Modified date: " + cal.getTime());
}
}Output
