Java programming consumer and producer, java programming producer

Create a new Break class to indicate the number of foods.

Public class Break {public static final int MAX = 10; // you can cook up to ten breads at a time. <Integer> Stack = new stack <Integer> (); public static int food_count = 0; // count the number of foods. // make a bread public synchronized void make_food (int number) {stack. push (number); food_count ++;} // eat food public synchronized int eat_food () {food_count --; return stack. pop ();}}

In the creation of a kitchen class, in order to make food or consume food, if there is no food, the consumer enters wait (), the producer starts to make food, and then wakes up the waiting consumer.

Public class Kitchen {private Break food; public static int people1_eatnumber = 0; // The number of breads that the first person eats. public static int people2_eatnumber = 0; // The second person eats public static final int TOTOAL_NUM = 100; // The total number of breads made public static int icount = 1; // count the number of breads made. public Kitchen (Break food) {this. food = food;} // method for making bread public synchronized void make () {if (food. food_count <10) {// is the pot full of food. make_food (Kitchen. icount); Syst Em. out. println ("finished" + Kitchen. icount +. "); Kitchen. icount ++; policyall (); // if the food is ready, contact two people to eat the bread} else {System. out. println ("the pot is full and ten are loaded at a time, waiting for the two to eat food. "); Try {wait ();} catch (InterruptedException e) {// TODO Auto-generated catch block e. printStackTrace ();} // enter the blocking status and wait for the consumer to wake up} // public synchronized void eat () {if (food. food_count> 0) {int temp = food. eat_food (); // The number of the bread. out. println (Thread. currentThread (). getName () + "eat" + temp + "food"); if (Thread. currentThread (). getName (). equals ("1") {people1_eatnumber ++;} else {people2_eatnumber + +;} Yyall (); // wake up and continue to make the bread} else {System. out. println ("the food has been eaten, waiting for a new cooking. "); Try {wait ();} catch (InterruptedException e) {// TODO Auto-generated catch block e. printStackTrace ();}}}}

The following describes the structure of the consumer and producer classes and passes them to a Kitchen object. The consumer calls the eating method in the Kitchen class.

public class consumer implements Runnable {    Kitchen kitchen;        public consumer(Kitchen kitchen){        this.kitchen = kitchen;    }    @Override    public void run() {        // 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();            }        }    }}

However, the producer calls the production method in the Kitchen object.

Public class product implements Runnable {private Kitchen kitchen; public product (Kitchen kitchen) {this. kitchen = kitchen ;}@ Override public void run () {// 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 is finished. ");}}

The following describes how to write the main class, including the main method, start the program, and create a test class:

Public class test {public static void main (String [] args) {Break brake = new Break (); Kitchen kitchen = new Kitchen (brake ); product p = new product (kitchen); consumer c1 = new consumer (kitchen); consumer c2 = new consumer (kitchen); Thread food = new Thread (p, "food "); thread lele1 = new Thread (c1, "1"); Thread people2 = new Thread (c2, "2"); food. start (); people1.start (); people2.start (); try {food. join (); people1.join (); people2.join ();} catch (Exception e) {e. printStackTrace ();} System. out. println ("I have eaten" + Kitchen. lele1_eatnumber); System. out. println ("2 eat" + Kitchen. people2_eatnumber );}}
