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

import java.util.Calendar;
public class AddSecondsToCurrentDate {
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 seconds to current date using Calendar.add method
now.add(Calendar.SECOND,100);
System.out.println("New time after adding 100 seconds : " + now.get(Calendar.HOUR_OF_DAY)
+ ":"
+ now.get(Calendar.MINUTE)
+ ":"
+ now.get(Calendar.SECOND));
/*
* Java Calendar class automatically adjust the date,hour or minutesaccordingly
* if adding seconds to the current time causes current minute, hour or date to be changed.
*/
//substract seconds from current time using Calendar.add method
now = Calendar.getInstance();
now.add(Calendar.SECOND, -50);
System.out.println("Time before 50 minutes : " + now.get(Calendar.HOUR_OF_DAY)
+ ":"
+ now.get(Calendar.MINUTE)
+ ":"
+ now.get(Calendar.SECOND));
}
}
/*
Typical output would be
Current time : 16:37:13
New time after adding 100 seconds : 16:38:53
Time before 50 minutes : 16:36:23
