多線程——模擬多人爬山

//Runnable的實現類，實現爬山的功能
public class ClimbThread implements Runnable{
    private int time;
    private int num = 5;
    
    public ClimbThread(int time) {
        this.time = time;
    }

    public void run() {
        while(true) {
            if(num == 0) {
                System.out.println(Thread.currentThread().getName()+"爬完了！");
                break;
            }
            System.out.println(Thread.currentThread().getName()+"爬完100米！");
            try {
                Thread.sleep(time);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            num--;
        }
        
    }
}

//測試類
public class Test {
    public static void main(String[] args) {
        ClimbThread user = new ClimbThread(500);
        ClimbThread user1 = new ClimbThread(1200);
        Thread thread = new Thread(user,"年輕人");
        Thread thread1 = new Thread(user1,"老年人");
        thread.start();
        thread1.start();
    }
}
