Java multithreading implementation of the ticket sales process

This paper uses Java multithreading to realize the function of simulating the ticket selling of multiple stations.

Keywords: Java multithreaded shared variable implementation runnable interface volatile thread synchronization.

The code is as follows

Ticket class

 PackageEx7_ticketsaler;/*multiple threads of the same object THREAD0/1/2, operations on shared variables count, need to declare the value of count as volatile * and because multiple threads operate on the same object ticket, so count is a resource-shared **/ Public classTicketImplementsrunnable{volatile intCount = 1000;//total number of votesBoolean flag =true; Object Locobj=NewObject (); @Override Public voidrun () {//TODO auto-generated Method Stub//the value of count does not get an error after joining a synchronization block                         while(count>0)            {//synchronized (locobj)//                {//                    //                    //                    //                }GetTicket (); }                            //handlers after the thread endsSystem.out.println (Thread.CurrentThread (). GetName () + "execution end \ n"); }        //defines a synchronization method This method can only be executed by one thread at a time, and another line friend can execute         Public synchronized voidGetTicket () {if(count>0) {Count--; System.out.println (Thread.CurrentThread ().
