Join methods in Java Multi-threading

Create a new thread with the following code:

1  Packagecom.thread.test;2 3  Public classMyThreadextendsThread {4     PrivateString name;5      PublicMyThread (String name) {6          This. Name =name;7     }8 @Override9      Public voidrun () {Ten          for(inti = 0; I < 100; i++) { OneSystem.out.println (name+ "[" +i+ "]"); A         } -         Super. Run (); -     } the}

After that, create a new test class with the following code:

1  Packagecom.thread.test;2 /*3 * 0-50 executes the main thread, 50-100 executes a thread, and the a thread executes completely before continuing the main thread4  */5  Public classthreaddemo{6      Public Static voidMain (string[] args) {7MyThread T =NewMyThread ("A");8 T.start ();9          for(inti = 0; I < 100; i++) {Ten             if(i>50) { One                 Try { A T.join (); -}Catch(interruptedexception e) { - e.printstacktrace (); the                 } -             } -System.out.println ("Main thread" + "[" +i+ "]"); -         } +     } -}

The following is an explanation of the join method in thread in the Java Platform SE8 API:

 Public Final voidJoinLongMillis)throwsInterruptedexceptionwaits at the most millis milliseconds for  ThisThread to die. A Timeout of 0means to wait forever. This implementation uses a loop of This. Wait calls conditioned on This. isAlive. As a thread terminates the This. Notifyall method is invoked. It is recommended this applications not use wait, notify, or Notifyall on Thread instances. Parameters:millis-The time to wait in milliseconds throws:illegalargumentexception-ifThe value of Millis is negative interruptedexception-ifAny thread have interrupted the current thread. The interrupted status of the current thread was cleared when ThisException is thrown.
