如何在JAVA中每隔一段時間執行一段程序

可以用線程來做，每隔幾秒開一個線程
代碼如下
public void runTask() {
final long timeInterval = 120000;// 兩分鍾運行一次
final ThreadService threadService = new ThreadService();
Runnable runnable = new Runnable() {
public void run() {
while (true) {
// ------- code for task to run
//你要運行的程序
// ------- ends here
try {
Thread.sleep(timeInterval);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
Thread thread = new Thread(runnable);
thread.start();
}
