Java – get the current system time and add 30 minutes after that

I want to get the current time in my application

I am starting and stopping time from my network service For example: ((start time) 11:00 a.m. to (stop time) 11:00 p.m.) now I want to add 30 minutes to the current time until the stop time arrives

Solution

Calendar Now = Calendar.getInstance();

Calendar Now = Calendar.getInstance();
Now.add(Calendar.MINUTE,30);

And output the time you can use

// 24 hours format
SimpleDateFormat df = new SimpleDateFormat("HH:mm");
// AM/PM format
SimpleDateFormat df = new SimpleDateFormat("hh:mm aa");

System.out.println(df.format(Now.getTime()));
