I am looking at the Date documentation and trying to figure out how I can express NOW + 5 seconds. Here's some pseudocode:
import java.util.Date public class Main { public static void main(String args[]) { Date now = new Date(); now.setSeconds(now.getSeconds() + 5); } } 
583
Easiest solution: if it is the current date use: Long seconds= 10; //update in seconds //seconds*1000 to convert second to millisecond Date dateAfterUpdation = new Date(System. currentTimeMillis() - (seconds*1000) );
To compute the elapsed time of an operation in seconds in Java, we use the System. currentTimeMillis() method.
currentTimeMillis() method returns the current time in milliseconds. The unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds.
Date is almost entirely deprecated and is still there for backward compatibility reasons. If you need to set particular dates or do date arithmetic, use a Calendar:
Calendar calendar = Calendar.getInstance(); // gets a calendar using the default time zone and locale. calendar.add(Calendar.SECOND, 5); System.out.println(calendar.getTime()); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
