所以我目前正在制作一个游戏（一个超过3500行代码的巨大游戏），并且在编写游戏的保存功能时，我碰到了一个error.it保存得很好，但是当我尝试负载，我保存的游戏它的一个文件返回一个错误：java游戏保存程序不会工作

Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "" 
    at java.lang.NumberFormatException.forInputString(Unknown Source) 
    at java.lang.Integer.parseInt(Unknown Source)

当你在调试器中运行它时，你学到了什么？ – 2012-02-26 15:22:06

扫描仪在错误发生之前仍然有输入，它停留在循环的非常重要的元素上，这基本上是我注意到的所有重要的东西 – 2012-02-26 15:24:27

好的。我认为如果你想在这里获得有用的帮助，你需要将其减少到一个最小的测试用例，它可以显示出问题（参见http://sscce.org）。 – 2012-02-26 15:26:05

我认为，当上次执行for循环{GroundState.Parse（scan.nextInt（））}语句scan.nextInt（）时，文件读指针位于行尾。然后调用nextLine（）将返回“”（空字符串）。所以你需要做的只是从处理中跳过这个特殊的空字符串。

不要打扰编写自己的对象持久代码 - 现有解决方案。对于您的数据，我建议您将游戏的状态作为对象存储。使用JAXB编组对象（即以XML格式写入磁盘）并解组对象（即通过读取XML文件来创建对象）。

JAXB不是很难使用。您可以在JAXB reference implementation页面阅读它。我是EclipseLink的JAXB提供商MOXy的粉丝。他们有一个非常容易遵循的getting started tutorial。

作为奖励，当您将保存游戏文件存储在XML中时，您可以使用任何文本编辑器打开它，并轻松读取游戏状态。这会让你的游戏更容易调试，因为游戏状态是人类可读的。用你目前的格式，你必须计算行数来查找值。

如果您不喜欢XML，那么请使用Java属性文件 - 即使这样做会比原始值更好。
