Add or substract minutes to current time using Java Calendar This example shows how to add or substract minutes in current time using Java Calendar class.

  
 import java.util.Calendar;  
 public class AddMinutesToCurrentDate {  
  public static void main(String[] args) {  
   //create Calendar instance  
   Calendar now = Calendar.getInstance();  
   System.out.println("Current time : " + now.get(Calendar.HOUR_OF_DAY)  
            + ":"  
            + now.get(Calendar.MINUTE)  
            + ":"  
            + now.get(Calendar.SECOND));  
   //add minutes to current date using Calendar.add method  
   now.add(Calendar.MINUTE,20);  
   System.out.println("New time after adding 20 minutes : "  
            + now.get(Calendar.HOUR_OF_DAY)  
            + ":"  
            + now.get(Calendar.MINUTE)  
            + ":"  
            + now.get(Calendar.SECOND));  
   /*  
    * Java Calendar class automatically adjust the date or hour accordingly  
 if adding minutes to the current time causes current hour or date to be changed.  
    */  
   //substract minutes from current date using Calendar.add method  
   now = Calendar.getInstance();  
   now.add(Calendar.MINUTE, -50);  
   System.out.println("Time before 50 minutes : " + now.get(Calendar.HOUR_OF_DAY)  
            + ":"  
            + now.get(Calendar.MINUTE)  
            + ":"  
            + now.get(Calendar.SECOND));  
  }
