Use interrupt to stop a thread

 

Public class mythread extends thread {

Public void run (){

While (! Thread. currentthread (). isinterrupted ()){

System. Out. println ("current thread id =" + thread. currentthread (). GETID ());

Try {

Thread. Sleep (500 );

} Catch (interruptedexception e ){

System. Out. println (thread. currentthread (). GETID () + "inturrupt ");

Break;

}

}

System. Out. println ("out run ");

}

}

 

 

 

 

Public class threadtest {

Public static void main (string ARGs []) {

Thread mythread1 = new mythread ();

Mythread1.start ();

Thread mythread2 = new thread (New mythread ());

Mythread2.start ();

Try {

Thread. Sleep (2000 );

} Catch (interruptedexception e ){

E. printstacktrace ();

}

Mythread2.interrupt ();

}

}

 

 

The running result is

Sometimes an exception occurs (when sleep is executed in the run loop)

Current thread id = 8

Current thread id = 10

Current thread id = 8

Current thread id = 10

Current thread id = 8

Current thread id = 10

10 inturrupt

Out run

Current thread id = 8

Current thread id = 8

Current thread id = 8

Current thread id = 8

 

Sometimes jump out of the while loop directly

Current thread id = 8

Current thread id = 10

Current thread id = 10

Current thread id = 8

Current thread id = 10

Current thread id = 8

Current thread id = 8

Out run

Current thread id = 8

Current thread id = 8

Current thread id = 8

Current thread id = 8
