I want to implement a timer for a game java?
提问by Technupe
I want to have a method startTimer(30)where the parameter is the amount of seconds to countdown. How do I do so in Java?

The Java 5 way of doing this would be something like:
Java 5 的做法是这样的：
void startTimer(int delaySeconds) {
Executors.newSingleThreadScheduledExecutor().schedule(
runnable,
delaySeconds,
TimeUnit.SECONDS);
}
The runnabledescribes what you want to do. For example:
在runnable描述你想要做什么。例如：
Runnable runnable = new Runnable() {
@Override public void run() {
System.out.println("Hello, world!");
}
}

java.util.Timeris not a bad choice, but javax.swing.Timermay be more convenient, as seen in this example.
java.util.Timer不是一个糟糕的选择，但javax.swing.Timer可能更方便，如本例所示。

import java.awt.*;
import java.util.Timer;
import java.util.TimerTask;
public class TimerDemo {
Toolkit toolkit;
Timer timer;
public TimerDemo(int seconds) {
toolkit = Toolkit.getDefaultToolkit();
timer = new Timer();
timer.schedule(new RemindTask(), seconds * 1000);
}
class RemindTask extends TimerTask {
public void run() {
System.out.println("Time's up!");
toolkit.beep();
System.exit(0);
}
}
public static void main(String args[]) {
System.out.println("About to schedule task.");
new TimerDemo(30);
System.out.println("Task scheduled.");
}
}
Many helpful links out there.

Helping presented solution by "Javascript is GOD", I do this, play a game at a specific time.
通过“Javascript is GOD”帮助提出的解决方案，我这样做，在特定时间玩游戏。
public static void main(String args[]) {
boolean flag = true;
while (flag) {
new TimerDemo(30);
game();
}
}
Notice that the flag variable changes within the game().
请注意，标志变量在game().
