一个不解的问题

[jackyyp]

public class test {
public static void main(String args[]){
MyThread myThread = new MyThread();
MyRunnable myRunnable = new MyRunnable();
Thread thread = new Thread(myRunnable);
myThread.start();
thread.start();
}
}
class MyThread extends Thread{
public void run(){
System.out.println("MyThread: run()");
}
public void start(){
System.out.println("MyThread: start()");
}
}
class MyRunnable implements Runnable{
public void run(){
System.out.println("MyRunnable: run()");
}
public void start(){
System.out.println("MyRunnable: start()");
}
}
为什么输出只是MyThread: start() MyRunnable: run()
而不输出MyThread: run()呢？

class MyThread extends Thread 继承后覆盖了Thread的start方法
所以调用start方法并不会自动启动线程的run方法。
当然输出只是MyThread: start()

[loveyousomuch]

Thread的start()(继承Runnable)方法是自动调用run()方法的，
而MyThread,MyRunnable类重写了start()方法，
而其中未调用run()方法！！
