我现在要每隔一段时间读取表里的数据,用哪种方式要好些?

import java.util.*;



public class TimePrinter implements Runnable
{

int pauseTime;

String name;

public TimePrinter(int x, String n)
{

pauseTime = x;

name = n;

}



public void run()
{

while(true)
{

try
{

System.out.println(name + ":" + new

Date(System.currentTimeMillis()));

Thread.sleep(pauseTime);

}
catch(Exception e)
{

System.out.println(e);

}

}

}



public static void main(String args[])
{

Thread t1 =
new Thread(new TimePrinter
(1000, "Fast Guy"));

t1.start();

Thread t2 =
new Thread(new TimePrinter
(3000, "Slow Guy"));

t2.start();



}

}
