Java : how to add 10 mins in my Time (8 answers)

Closed 5 years ago.

I have a date variable (endTime) with some value (eg : 10:40). I need to create a new variable by adding 10 minutes to endTime. How can I do it?

Thanks in advance

public static  String endTime = "";
DateFormat timeFormat = new SimpleDateFormat("HH:mm:ss");
Calendar cal = Calendar.getInstance();

endTime = timeFormat.format(cal.getTime());`

You can use add method on your Calendar:

public static  String endTime = "";
DateFormat timeFormat = new SimpleDateFormat("HH:mm:ss");
Calendar cal = Calendar.getInstance();

cal.add(Calendar.MINUTE, 10)

endTime = timeFormat.format(cal.getTime());`

Found in Javadoc, it takes me 30 seconds.
