Java custom Timer

In Java, the timer function does not have the pause and continue timing function. Therefore, if you want to implement these two functions, you can write a timer by yourself. Below is a Timer class that I write myself.

The Code is as follows:

// Timer public class keeptime {private long s = 0; private Boolean tm_flag; private mytask MT; Public keeptime () {}// start timing public void start_time () {If (MT = NULL) {Mt = new mytask (); tm_flag = true; Mt. start () ;}// stop the public void stop_time () {This. tm_flag = false; this. mt = NULL;} private class mytask extends thread {@ overridepublic void run () {While (tm_flag) {// system. out. println (S + ""); s ++; try {thread. sleep (1000);} catch (interruptedexception e) {e. printstacktrace () ;}}}// get time public long gettime () {return s ;}// reset time public void resettime () {This. S = 0 ;}public Boolean gettmfalg () {return tm_flag ;}}

Start and continue to call start_time, stop and pause call stop_time,

Some people may ask why th_flag is not directly controlled by setting th_flag. I used to set th_flag to false and the thread will not be available,

So we need to re-open a thread, which is often used in games.
