Thread 两种实现方式的区别

[code]package thread.ticket;

class Ticket1 extends Thread{
    public Ticket1(String name)
    {
        super(name);
        }
    int num=50;

    public void run() {
        for (int i = 0; i < 200; i++) {
            if(num>0)
            {
                System.out.println(getName()+"卖出第"+num-- +"张");

            }
        }
    }

}
public class TicketDemo {
    public static void main(String[] args) {
    //3个窗口卖
        new Ticket1("A").start();
        new Ticket1("B").start();
        new Ticket1("C").start();
    }
}

/**
 *      比较两种方式的区别:
 *          
 *          使用继承方式,资源不能共享;
 *
 *          继承方式,继承了Thread类之后,就不能再继承其他类了;
 *
 *          
 *          从代码的简单性来性,来说继承方式简单些
 *
 *
 *      推荐使用 接口方法,  方便以后拓展,资源共享
 *          
 *
