Java 两种实现多线程的区别

class MyThread extends Thread{
    private int ticket = 10;
    public void run() {
        for(int i = 0; i < 10; i++) {
            if(this.ticket > 0) {
                System.out.println("正在卖第" + (this.ticket--) + "张票");
            }
        }
    }
}

public class Test1 {
    public static void main(String[] args) {
        MyThread mt1 = new MyThread();
        MyThread mt2 = new MyThread();
        MyThread mt3 = new MyThread();
        mt1.start();
        mt2.start();
        mt3.start();
    }
}

class MyThread implements Runnable{
    private int ticket = 10;
    public void run() {
        for(int i = 0; i < 10; i++) {
            if(this.ticket > 0) {
                System.out.println("正在卖第" + (this.ticket--) + "张票");
            }
        }
    }
}

public class Test1 {
    public static void main(String[] args) {
        MyThread mt = new MyThread();
        // 3 个线程同时占用着 mt
        new Thread(mt).start();
        new Thread(mt).start();
        new Thread(mt).start();
    }
}
