Java uses threadfactory to create a new thread

The first step is to build the thread wrapper class Workthread, which is primarily designed to enable better management of threads

public class workthread extends thread {     private  runnable target;   //Thread Execution Target     private atomicinteger counter ;        public workthread (Runnable target, atomicinteger  counter)  {          this.target =  target;          this.counter = counter;       }       @Override       Public void run ()  {          try {               target.run ();           } finally {                int c = counter.getanddecrement ();               system.out.println ("terminate no "  + c +  "  Threads ");           }      }   }

Second, to define a test target

public class Workrunnable implements runnable{@Overridepublic void Run () {System.out.println (' complete a Task ');}}

Ways to implement a threading factory

public class Workthreadfactory implements threadfactory{private Atomicinteger Atomicinteger = new Atomicinteger (0);                  Overridepublic Thread Newthread (Runnable r) {int c = atomicinteger.incrementandget ();  System.out.println ("Create no" + C + "Threads"); return new Workthread (R, Atomicinteger);//counter to better manage threads}}

Test Thread Factory

Public class testthreadfactory {public static void main (String[] args)  {//Create thread (concurrency) pool, auto scale (automatic conditional thread pool size) Executorservice es =  executors.newcachedthreadpool (new  workthreadfactory ());//Concurrent with 5 worker threads Es.execute (new workrunnable ()); Es.execute (New workrunnable ()) ; Es.execute (New workrunnable ()); Es.execute (New workrunnable ()); Es.execute (New workrunnable ()); /indicates that the thread pool and worker threads are closed when all threads have finished executing, and if this method is not called, the JVM does not automatically shut down        es.shutdown ();           try {            //wait for the thread to finish executing, not more than 2*60 seconds, with shutdown           Es.awaittermination (2*60, timeunit.seconds);       } catch  ( Interruptedexception e)  {               e.printstackTrace ();        }  }}
