BufferedWriter表现得很奇怪 [英] BufferedWriter is acting strange

问题描述

我正在尝试使用工作高分机制制作游戏，我正在使用java.io.BufferedWriter写入高分文件。我在高分上没有加密，我使用Slick2D和LWJGL进行渲染和用户输入。程序执行此代码：

I am trying to make a game with a working highscore mechanism and I am using java.io.BufferedWriter to write to a highscore file. I don't have an encryption on the highscore and I am using Slick2D and LWJGL for rendering and user input. The program executes this code:

FileWriter fstream = new FileWriter("res/gabjaphou.txt");

BufferedWriter writer = new BufferedWriter(fstream);

writer.write(score); // score is an int value

writer.close(); // gotta save m'resources! lol

我打开由此生成的文本文件，所有读取的内容都是问号。我不知道为什么会发生这种情况，我使用了我正在制作的另一个项目的其他代码，我对此没有任何问题......有谁知道为什么？这真烦人！ ：C

I open the text file generated by this and all it reads is a question mark. I don't know why this happens, and I used other code from another project I was making and I had no problem with that... Does anyone know why? This is really annoying! :C

推荐答案

BufferedWriter.write（int）用于编写单个字符，而不是整数。

BufferedWriter.write(int) is meant to write a single charecter, not a integer.

public void write（int c）

throws IOException

写一个字符。

覆盖：写在类Writer中

参数： c - int 指定要写的字符

抛出： IOException - 如果发生I / O错误

Overrides: write in class Writer
Parameters: c - int specifying a character to be written
Throws: IOException - If an I/O error occurs

尝试

writer.write(String.valueOf(score));
