这篇博客主要是通过模拟生活中的生产者消费者的案例，来进一步熟悉线程的相关操作。
/** * 生产者---厨师 */class PRoductor implements Runnable { private Food food; public Productor(Food food) { this.food = food; } @Override public void run() { for (int i = 0; i < 100; i++) { if (i % 2 == 0) { food.set("韭菜炒鸡蛋","男人的好食品，多吃有益健康"); } else { food.set("葱爆腰花","补肾气,通膀胱，我好她也好"); } } }}/** * 消费者---服务员 */class Consumer implements Runnable{ private Food food; public Consumer(Food food) { this.food=food; } @Override public void run() { for (int i=0;i<100;i++){ food.get(); } }}/** * 产品---食物 */class Food{ private String name; private String content; //标记变量 private boolean flag=true; //true表示可以生产，false表示可以消费 public synchronized void set(String name,String concent) { if(!flag) { try { this.wait();//让当前线程进入等待池等待，没有指定时间， // 需要其它线程唤醒，释放对象锁，让出CPU //sleep释放CPU，不释放对象锁住 } catch (InterruptedException ex) { ex.printStackTrace(); } } this.setName(name); try { Thread.sleep(300); } catch (InterruptedException ex) { ex.printStackTrace(); } this.setContent(concent); flag=false;//表示可以消费 this.notify();//唤醒在该监视器上的一个线程 } //消费产品 public synchronized void get() { if(flag) { try { this.wait(); }catch (InterruptedException ex) { ex.printStackTrace(); } } try { Thread.sleep(300); }catch (InterruptedException ex) { ex.printStackTrace(); } System.out.println(this.getName()+":"+this.getContent()); flag=true; this.notify(); } public Food() { } public Food(String name, String content) { this.name = name; this.content = content; } public String getName() { return name; } public String getContent() { return content; } public void setName(String name) { this.name = name; } public void setContent(String content) { this.content = content; } @Override public String toString() { return "Food{" + "name='" + name + '/'' + ", content='" + content + '/'' + '}'; }}public class ThreadDemo { public static void main(String args[]) { Food food=new Food(); Productor productor=new Productor(food); Consumer consumer=new Consumer(food); new Thread(productor).start(); new Thread(consumer).start(); }}新闻热点
