Consumers and producers of Java programming

Creates a new break class that represents the quantity of food.

 Public classBreak { Public Static Final intMAX = 10;//Cook up to 10 loaves of bread at oncestack<integer> stack =NewStack<integer>();  Public Static intFood_count = 0;//count the number of food//Make Bread     Public synchronized voidMake_food (intNumber )        {Stack.push (number); Food_count++; }        //Eat food     Public synchronized intEat_food () {Food_count--; returnStack.pop (); }}

In creating a kitchen class, in order to make food or consume food, if the food is not there, the consumer enters wait (), the producer starts to make the food, and then wakes the waiting consumer.

 Public classKitchen {PrivateBreak food ;  Public Static intPeople1_eatnumber = 0;//the number of bread the first person eats     Public Static intPeople2_eatnumber = 0;//the number of loaves eaten by the second person     Public Static Final intTotoal_num = 100;//total amount of bread made     Public Static inticount = 1;//Count The amount of bread that has been made         PublicKitchen (break food) { This. Food =Food ; }        //the way to make bread     Public synchronized voidMake () {if(FOOD.FOOD_COUNT<10) {//the pot is not fullFood.make_food (Kitchen.icount); System.out.println ("Finished the first" +kitchen.icount+ "food. "); Kitchen.icount++; Notifyall ();//The food is there, find two people to eat bread}Else{System.out.println ("The pot is full, one-time pack of 10, waiting for two people to eat food." "); Try{wait (); } Catch(interruptedexception e) {//TODO auto-generated Catch blockE.printstacktrace (); }//into a blocking state, waiting for the consumer to wake up        }    }        //the way to eat bread     Public synchronized voideat () {if(food.food_count>0){            inttemp = Food.eat_food ();//the number of the bread eatenSystem.out.println (Thread.CurrentThread (). GetName () + "ate the first" +temp+ "food"); if(Thread.CurrentThread (). GetName (). Equals ("Number One")) ) {People1_eatnumber++; }Else{People2_eatnumber++;  } notifyall (); //wake up and continue making bread}Else{System.out.println ("The food is finished and waiting to be re-cooked. "); Try{wait (); } Catch(interruptedexception e) {//TODO auto-generated Catch blockE.printstacktrace (); }        }    }}

The following goes into the structure of the consumer and producer classes, passed to a kitchen object, where the consumer invokes the kitchen class in the eating method.

 Public classConsumerImplementsRunnable {Kitchen Kitchen;  Publicconsumer (Kitchen Kitchen) { This. Kitchen =Kitchen; } @Override Public voidrun () {//TODO auto-generated Method Stub         while(true){            if(kitchen.icount>100&&break.food_count<=0){                 Break; }            Try{kitchen.eat (); Thread.Sleep (100); }Catch(Exception e) {e.printstacktrace (); }        }    }}

The producer, however, invokes the authoring method in the kitchen object.

 Public classProductImplementsRunnable {PrivateKitchen Kitchen;  Publicproduct (Kitchen Kitchen) { This. Kitchen =Kitchen; } @Override Public voidrun () {//TODO auto-generated Method Stub         while(true){            //End this thread            if(Kitchen.icount > 100){                 Break; }            Try{kitchen.make (); Thread.Sleep (100); }Catch(Exception e) {e.printstacktrace (); }} System.out.println ("The kitchen food material has been finished. "); }}

The following begins the main class, including the main method, starting the program, and creating a test class that implements:

 Public classTest { Public Static voidMain (string[] args) {Break brake=NewBreak (); Kitchen Kitchen=NewKitchen (brake); Product P=Newproduct (kitchen); Consumer C1=Newconsumer (kitchen); Consumer C2=Newconsumer (kitchen); Thread Food=NewThread (p, "food"); Thread People1=NewThread (C1, "number One")); Thread People2=NewThread (C2, "number second");        Food.start ();        People1.start ();                People2.start (); Try{food.join ();            People1.join ();        People2.join (); }Catch(Exception e) {e.printstacktrace (); } System.out.println ("One eat" +kitchen.people1_eatnumber); System.out.println ("Number second Eats" +kitchen.people2_eatnumber); }}
