如何暂停我的 Java 程序 2 秒钟 [英] How to pause my Java program for 2 seconds

问题描述

我是 Java 新手，正在制作一个用于练习的小游戏.

I'm new to Java and making a small game for practice.

if (doAllFaceUpCardsMatch == false) {
        //run pause here//
        concentration.flipAllCardsFaceDown();
} else {
        concentration.makeAllFaceUpCardsInvisible();
}

我想在此之前暂停游戏两秒钟

I want to pause the game for two seconds here before it does

concentration.flipAllCardsFaceDown();

我将如何暂停它?

推荐答案

您可以使用:

 Thread.sleep(2000);

或

java.util.concurrent.TimeUnit.SECONDS.sleep(2);

请注意，这两个方法都会抛出InterruptedException，这是一个已检查的异常，因此您必须捕获它或在方法中声明.

Please note that both of these methods throw InterruptedException, which is a checked Exception, So you will have to catch that or declare in the method.

捕获异常后，您的代码将如下所示:

After Catching the exception, your code will look like this:

if (doAllFaceUpCardsMatch == false) {
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        concentration.flipAllCardsFaceDown();
} else {
        concentration.makeAllFaceUpCardsInvisible();
}

由于您是新手，我建议您在熟悉 Java 后学习如何进行异常处理.

Since you are new, I would recommend learning how to do exception handling once you are little bit comfortable with java.
