生产者消费者模型是并发编程中比较经典的问题，其他的不多说，直接给出代码
线程同步采用synchronized，当然了，使用ReentrantLock或者Semaphore进行线程之间的通信也完全可以；

public class StringTest {    public static void main(String[] args) {        /*生产者消费者模型*/        Product product = new Product();        Thread produce = new Thread(new ProduceProduct(product));        produce.setName("生产者1 ");        Thread comsume = new Thread(new ConsumeProduct(product));        comsume.setName("消费者1 ");        Thread comsume2 = new Thread(new ConsumeProduct(product));        comsume2.setName("消费者2 ");        produce.start();        comsume.start();        comsume2.start();        }    }    static class Product{        private int max_product = 10;        private int min_product = 0;        private int product = 0;        public Product(int max_product){            this.max_product = max_product;        }        public Product(){        }        public synchronized void produceProduct(){            if (this.product >= max_product) {                try{                    System.out.println("产品已经足够，请稍等");                    wait();                }catch (Exception e) {                }                return;            }            product++;            System.out.println(Thread.currentThread().getName() + " 生产了第：" + product + "个产品");            notifyAll();        }        public synchronized void comsumeProduct(){            if (this.product <= min_product) {                try{                    System.out.println("产品不够了，请稍等");                    wait();                }catch (Exception e) {                }                return;            }            System.out.println(Thread.currentThread().getName() + "消费了第：" + product + " 个产品");            product--;            notifyAll();        }    }    static class ConsumeProduct implements Runnable{        private Product product;        public ConsumeProduct(Product product) {            this.product = product;        }        @Override        public void run() {            System.out.println("开始消费产品");            while(true){                try {                    Thread.sleep(2000);                } catch (InterruptedException e) {                    e.printStackTrace();                }                product.comsumeProduct();            }        }    }    static class ProduceProduct implements Runnable{        private Product product;        public ProduceProduct(Product product) {            this.product = product;        }        @Override        public void run() {            System.out.println("开始生产产品");            while (true) {                try{                    Thread.sleep(1000);                }catch (Exception e) {                }                product.produceProduct();            }        }    }}
