使用 BufferedWriter 和 FileWriter 库重写文件

Question

我目前正在开发一款游戏，我很难覆盖保存文件。我已经看到如何清除文件，然后稍后重写它，但我想要一些能够覆盖文件的东西。我正在使用 BufferedWriter 和 FileWriter 库。这是我正在使用的代码：

    System.out.println("Congratulations! You beat the first maze! Thanks for playing!\nBefore you go, please answer this one question.");
    System.out.println("Please enter a color of the following choices.\nBlack, Navy, Dark Gray, Gray, Light Gray, Purple, Olive, Pink, White, or\nYellow.");
    String fave = kb.nextLine();
    BufferedWriter writer = null;
    try {
        writer = new BufferedWriter(new FileWriter(newFile("colorchoice.txt"),true));
        writer.write(fave);
    } catch (Exception ex) {
        ex.printStackTrace();
    } finally {
        try {
            writer.close();
        } catch (Exception ex) { /*ignore*/ }
    }
    try {
        writer.flush();
        writer.setLength(0);
        writer = new BufferedWriter(new FileWriter(new File("save.txt"), true));
        writer.write(name);
        writer.newLine();
        writer.write(choice4);
        writer.newLine();
        if (choice == 1 || choice == 2) {
            writer.write(gender2);
            writer.newLine();
        }
        writer.write(col);
        writer.newLine();
        writer.write(dead2);
        writer.newLine();
    } catch (Exception ex) {
        ex.printStackTrace();
    } finally {
        try {
            writer.close();
        } catch (Exception ex) { /*ignore*/ }
    }
    System.exit(0);

忽略 println 语句，我可以在 BufferedWriter 或 FileWriter 中做些什么来覆盖文件吗？还是我需要更改对其他库的导入才能使覆盖工作？

感谢任何帮助。

Answer 1

writer = new BufferedWriter(new FileWriter(newFile("colorchoice.txt"),true));

在append 参数中将true 更改为false。
