java-多线程卖票

一、继承Thread

/**

public class MyThreadTest extends Thread {

    private static int ticket = 100;

    public void run() {
        while (true) {
            synchronized (MyThreadTest.class) {
                if (ticket > 0) {
                    try {
                        Thread.sleep(100);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    System.out.println(Thread.currentThread().getName() + "..." + ticket--);
                } else {
                    break;
                }
            }
        }
    }

    public static void main(String[] args) {
        MyThreadTest t1 = new MyThreadTest();
        MyThreadTest t2 = new MyThreadTest();
        MyThreadTest t3 = new MyThreadTest();

        t1.setName("窗口1");
        t2.setName("窗口2");
        t3.setName("窗口3");

        t1.start();
        t2.start();
        t3.start();
    }

}

二、实现runnable接口

package Thread;

public class MyRunnableTest implements Runnable {
    private int ticket = 20;
    @Override
    public void run() {
        while (true) {
            synchronized (this) {
                try {
                    Thread.sleep(100);  //更好的体现结果
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                if (ticket > 0) {
                    System.out.println(Thread.currentThread().getName() + "......" + ticket--);
                }
            }
        }
    }
}

class RunnableStart {
    public static void main(String[] args) {
        MyRunnableTest myRunnableTest = new MyRunnableTest();
        Thread t1 = new Thread(myRunnableTest, "窗口1");
        Thread t2 = new Thread(myRunnableTest, "窗口2");
        t1.start();
        t2.start();
    }
}
