Java multi-thread distribution movie ticket

Code:

1  Public classMainClass {2 3      Public Static voidMain (string[] args) {4 method1 ();5     }6      Public Static voidmethod1 () {7Sellmovie sell =NewSellmovie ();8         9         NewThread (Sell, "American"). Start ();Ten         NewThread (Sell, "glutinous rice"). Start (); One     } A}

1  Public class Model {2     int total = ten; 3 }

1  Public classSellmovieImplementsRunnable {2Model model =NewModel ();3 4 @Override5      Public voidrun () {6          while(Model.total > 0) {7             synchronized(model) {//can only lock reference type8             9                 if(Model.total > 0) {TenSystem.out.println ("Sales Ticket:" + model.total + "+" +Thread.CurrentThread (). GetName ()); One}Else { ASystem.out.println ("Tickets sold out"); -                     return; -                 } themodel.total--; -             } -System.out.println ("......")); -         } +     } -}

This example realizes multi-threading through the implementation of the Runnable interface method, here is the "American Regiment" and "Glutinous rice" two sub-thread Rob ticket process.

Since the lock is only a reference type, the remaining number of votes is shown in the form of the Model class property.

The following results are output:

Ticketing: 10 American
.............
Ticketing: 9 glutinous rice
.............
Ticketing: 8 American
.............
Ticketing: 7 American
.............
Ticketing: 6 glutinous rice
.............
Ticketing: 5 American
.............
Ticketing: 4 glutinous rice
.............
Ticketing: 3 American
.............
Ticketing: 2 American
.............
Ticketing: 1 American
