所以，问题来了。我正在制作一款游戏，但在保存进度的文件保存类方面遇到了问题。它能够加载文件中的默认值来创建新游戏，然后重新启动游戏以使更改生效。问题是，默认值被保存，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，然后游戏会识别它。这是我使用的类:
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import mario.simulator.MarioSimulator;

任何帮助都是有帮助的。
最佳答案
基本上，您将忽略保存文件(如果存在)...
f = new File("resource\\config\\save.sav");
if(!f.exists()){
//...
} // And then what??
相反，您应该重置该文件，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);
}
确保您正在管理您的读者并尽最大努力确保它们适当关闭，请记住，如果您创建，则应该关闭它。
如果您使用的是 Java 7+，则可以使用 try-with-resources如上所述，否则您应该有一个 finally 子句来关闭您可能已打开的资源(每个子句可能需要自己的 try-catch)
