Java 多线程的两种实现方式

class IphoneThread extends Thread {
    public int iphone = 5;
    public String user;

    public IphoneThread(String str) {
        user = str;
    }

    @Override
    public void run() {
        while (iphone != 0) {
            iphone--;
            System.out.println(user + " get one and left iphone num=" + iphone);
        }
    }
}

public class ThreadTest {
    public static void main(String[] arg) {
        IphoneThread t1 = new IphoneThread("Toms");
        t1.start();
        IphoneThread t2 = new IphoneThread("Jack");
        t2.start();
        IphoneThread t3 = new IphoneThread("Boom");
        t3.start();
    }
}

class IphoneRunable implements Runnable {

    public int iphone = 5;

    @Override
    public void run() {
        while (iphone != 0) {
            iphone--;
            System.out.println(Thread.currentThread().getName()
                    + " get one and left iphone num=" + iphone);
        }

    }

}

public class RunableTest {
    public static void main(String[] arg) {
        IphoneRunable runable = new IphoneRunable();
        Thread t1 = new Thread(runable, "Toms");
        t1.start();
        Thread t2 = new Thread(runable, "Jack");
        t2.start();
        Thread t3 = new Thread(runable, "Boom");
        t3.start();
    }
}
