文件在Java中无法正常工作

java file

文件在Java中无法正常工作,java,file,Java,File,所以，问题来了。我正在制作一个游戏，我在保存进度的文件保存类中遇到了问题。它可以加载文件中的默认值来创建新游戏，然后重新启动游戏，以便更改生效。问题是，默认值已保存，但游戏不再识别它们。然后，当我手动删除该文件时，使用相同的方法重新创建该文件，然后游戏识别它。以下是我使用的类： import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.File; import java.io.FileReader;

任何帮助都是有用的。

基本上，如果保存文件存在，您将忽略它

f = new File("resource\\config\\save.sav");
if(!f.exists()){
    //...
} // And then what??
相反，您应该重置文件，然后加载它

f = new File("resource\\config\\save.sav");
if(!f.exists()){
    filer.reset();
}
try (BufferedReader br = new BufferedReader(new FileReader(f))) {
    // Load the file...
} catch (IOException ex) {
    Logger.getLogger(filer.class.getName()).log(Level.SEVERE, null, ex);
}
确保你在管理你的读者，并尽最大努力确保他们被适当地关闭，记住，如果你创建了，你应该关闭它

如果您使用的是Java 7+，您可以如上所示使用，否则您应该有一个
finally
子句，该子句将关闭您可能打开的资源（每个资源可能都需要自己的
try catch
）

我知道我做了什么。程序仅在文件不存在时读取该文件！那只是我没有注意我的代码。也许，如果我能更好地组织一切，调试会更容易，如下所示：

你所说的“游戏不再识别它们”是什么意思？如果文件存在，你的构造函数不会做任何事情。我相当确信
file
在Java中工作正常。至于你的程序，我也相信它不能正常工作。最后，需要帮助-使用。你说的“游戏不再识别它们”是什么意思？如果文件存在，你的构造函数不会做任何事情。我非常确信
