TimerTask抛不出运行时异常

用J2SE和Android，都运行相同的TimerTask，表现

1. Java代码

import java.util.Timer;
import java.util.TimerTask;

public class ddd {

    public static void main(String[] args) throws Exception {
        Timer timer = new Timer();
        timer.schedule(new Task(), 10, 1000);
    }

    static class Task extends TimerTask {

        public void run() {
            System.out.println("**");
            int i = 5 / 0;
            System.out.println(i);

        }

    }

}

2. Andrdoi代码

import android.app.Activity;
import android.os.Bundle;

import java.util.Timer;
import java.util.TimerTask;

public class ddd extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Timer timer = new Timer();
        timer.schedule(new Task(), 10, 1000);
    }

    static class Task extends TimerTask {

        public void run() {
            System.out.println("**");
            int i = 5 / 0;
            System.out.println(i);

        }

    }
}

 表现为，J2SE程序会因java.lang.ArithmeticException: / by zero挂掉。Android程序会每隔一秒打印一行“**”，就是说错误代码没有抛出异常，而是被简单的忽略掉。

所以，开发TimerTask时要小心的处理异常，把可能抛出的异常都catch住处理掉。
