用多线程的生产者消费者模式实现工厂的面包运到超市，顾客去超市购买，超市每次最大存储6个面包。

public class Test1Consumer {public static void main(String[] args) {Supermarkt s = new Supermarkt();Factory f = new Factory(s);Consumer c = new Consumer(s);Thread t = new Thread(f, "工厂");Thread t1 = new Thread(c, "顾客");t.start();t1.start();}}class Brand {int id;String name;public Brand(int id, String name) {super();this.id = id;this.name = name;}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}class Supermarkt {Brand b[] = new Brand[6];int index = -1;// 运面包public synchronized void addBrand(Brand brand) throws InterruptedException {if (index >= 5) {this.wait();}index++;b[index] = brand;System.out.println(Thread.currentThread().getName() + "卖了"+ brand.getId() + "个" + brand.getName() + "的面包,超市一共还有"+ (index + 1) + "个");this.notifyAll();}// 卖面包public synchronized void saleBrand() throws InterruptedException {if (index <= -1) {this.wait();}// 打印卖出去面包的信息System.out.println(Thread.currentThread().getName() + "买掉了"+ b[index].getId() + "个" + b[index].getName() + "的面包,超市还剩下"+ (index) + "个");index--;this.notifyAll();}}class Factory implements Runnable {Supermarkt markt;public Factory(Supermarkt markt) {super();this.markt = markt;}@Overridepublic void run() {for (int i = 0; i < 80; i++) {try {markt.addBrand(new Brand(1, "难吃"));} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}class Consumer implements Runnable {Supermarkt sup;public Consumer(Supermarkt sup) {super();this.sup = sup;}@Overridepublic void run() {for (int i = 0; i < 80; i++) {try {sup.saleBrand();} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}
