Subtract minutes from current time using Calendar.add() method in Java
Import the following package for Calendar class in Java.
import java.util.Calendar;
Firstly, create a Calendar object and display the current date and time.
Calendar calendar = Calendar.getInstance();
System.out.println("Current Date and Time = " + calendar.getTime());Now, let us decrement the minutes using the calendar.add() method and Calendar.MINUTE constant. Set a negative value since you want to decrease the minutes.
calendar.add(Calendar.MINUTE, -15);
Example
import java.util.Calendar;
public class Demo {
public static void main(String[] args) {
Calendar calendar = Calendar.getInstance();
System.out.println("Current Date = " + calendar.getTime());
// Subtract 15 minutes from current date
calendar.add(Calendar.MINUTE, -15);
System.out.println("Updated Date = " + calendar.getTime());
}
}Output
Current Date = Thu Nov 22 16:26:19 UTC 2018 Updated Date = Thu Nov 22 16:11:19 UTC 2018
