Java Thread producer Consumer

See the Bi Xiangdong Teacher's producer consumers, just follow the video reference run a bit, feel okay

What is worth learning is that the organization is particularly clear:

Producterconsumerdemo.java, a resource class resources, the producer consumers can access to.

Producer Class Producter, consumer consumer have implemented the Runnable interface, in which the Run method to implement overloading, the sharing of resources for production and consumption

Optimization:

If you later need to join the project, add a constructor method to the Producterconsumerdemo class, public Producterconsumerdemo () {...}, instantiate the object to invoke

Code:

1 classProducterconsumerdemo2 {3      Public Static voidMain (string[] args)4     {5Resources r =NewResources ();6Productor Pro =NewProductor (r);7Consumer con =NewConsumer (r);8         9Thread T1 =NewThread (pro);TenThread t2 =NewThread (con); One T1.start (); A T2.start (); -System.out.println ("Hello world!"); -     } the } -  - classResources - { +     PrivateString name; -     Private intCount =1; +     Private BooleanFlag =false; A  at      Public synchronized voidset (String name) -     { -        if(flag) -            Try{ This. Wait ();}Catch(Exception e) {} -         This. Name = name+ "--" +count++; -  inSystem.out.println (Thread.CurrentThread (). GetName () + "producer" + This. Name); -Flag =true; to        //Wake up the other party process +         This. Notify (); -  the     } *      Public synchronized voidout () $     {Panax Notoginseng        if(!flag) -            Try{ This. Wait ();}Catch(Exception e) {} the         +System.out.println (Thread.CurrentThread (). GetName () + ".... Consumer .... "+ This. Name); AFlag =false; the        //Wake up the other party process +         This. Notify (); -  $     } $ } -  - classProductorImplementsRunnable the { -     PrivateResources Res;Wuyi Productor (Resources res) { the          This. res =Res; -     } Wu      Public voidrun () { -          while(true){ AboutRes.set ("+ + products + +"); $         } -     } -  - } A  + classConsumerImplementsRunnable the { -     PrivateResources Res; $ Consumer (Resources res) { the          This. res =Res; the     } the      Public voidrun () { the          while(true){ - res.out (); in         } the     } the  About}

Because the function that you need is that the producer consumer operates on a two-dimensional array, the member properties of the resource resources class are added on top of it. Implement Access functions

It is a frame, retained:

Of course, this is only for supporting two separate threads, if you continue to join multiple threads (>2) will certainly have the problem of resource data error, continue to learn
