Java threads Stop, pause, and continue

The thread-stopping method in the thread class has a stop (), and the method of pausing and continuing the thread has suspend () and resume (). However, these methods have been abandoned.

Exception method Stop thread

On the code:

 Public classTest { Public Static voidMain (string[] args) {MyThread thread=NewMyThread ();            Thread.Start (); Try{Thread.Sleep (1000); } Catch(interruptedexception e) {e.printstacktrace ();    } thread.interrupt (); }}classMyThreadextendsThread {@Override Public voidrun () {BooleanFlag =true;  while(flag) {if( This. isinterrupted ()) {System.out.println ("Thread is about to stop"); Try {                    Throw Newinterruptedexception (); } Catch(interruptedexception e) {flag=false; }}} System.out.println ("The loop has jumped out and the thread stops"); }}

Print output:

The thread is about to stop and the thread stops.

When the Run method finishes executing, the thread will naturally end.

To stop a thread using return

 Public classTest2 { Public Static voidMain (string[] args) {MyThread2 thread=NewMyThread2 ();        Thread.Start (); Try{Thread.Sleep (1000); } Catch(interruptedexception e) {e.printstacktrace ();    } thread.interrupt (); }}classMyThread2extendsThread {@Override Public voidrun () { while(true) {            if( This. isinterrupted ()) {System.out.println ("Thread Stop"); return; }        }    }}

Print output:

Thread stop

Thread paused and resumed

Thread paused, resumed, and stopped, on the code:

 Public classTest { Public Static voidMain (string[] args) {MyThread thread=NewMyThread ();        Thread.Start (); Try{Thread.Sleep (1);            Thread.mysuspend (); Thread.Sleep (1);            Thread.myresume (); Thread.Sleep (1);        Thread.mystop (); } Catch(Exception e) {e.printstacktrace (); }    }}classMyThreadextendsThread {Private intCounts = 0; Private intStatus = 1; Private Final intSUSPEND =-1; Private Final intRUNNING = 1; @Override Public voidrun () {BooleanFlag =true;  while(flag) {if( This. isinterrupted ()) {System.out.println (++counts + "-thread is about to stop"); Try {                    Throw Newinterruptedexception (); } Catch(interruptedexception e) {flag=false; }            } Else if(Status = =SUSPEND) {System.out.println (++counts + "-Thread paused"); } Else if(Status = =RUNNING) {System.out.println (++counts + "-thread is still continuing"); }} System.out.println (++counts + "-already jumping out of the loop, thread stopped"); }     Public voidMysuspend () {Status=SUSPEND; }    synchronized  Public voidMyresume () {Status=RUNNING;  This. Notifyall (); }     Public voidMystop () { This. Interrupt (); }}

Print output:
