【问题描述】：

我正在尝试以 UTF_8 格式保存一个 .txt 文件，但我不明白应该将它添加到我的代码的哪个位置。这是我得到的。

String fileStringName =  userHome + "/wordsearch directory/Puzzle.txt";
        File filePath = new File(userHome + "/wordsearch directory/Puzzle.txt");
        File dirPath = new File (userHome + "/wordsearch directory");           
        //new method just made
        //make pop up jpane displaying puzzle ID.
        boolean filePathExists = false;
        if(!filePath.exists())
        {
            filePathExists = dirPath.mkdirs();
            try {
                //BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(path),"UTF-8"));
                writer = new PrintWriter(new BufferedWriter(new FileWriter(fileStringName,  true)));
        //  Writer writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fileStringName), "UTF-8"));
            } catch (IOException e2) {
                writer = null;
                e2.printStackTrace();
            }
            writer.printf(savePuzzle.toString());
            writer.printf("\n");
            writer.close();

this answer/问题对你有帮助吗？
好吧，你的 cmets 似乎得到了正确的想法，只是你没有用 PrintWriter 包裹你的 BufferedWriter。
看起来怎么样？
我似乎无法正确理解语法。

【解决方案1】：

试试这个：

File dirPath = new File (userHome + "/wordsearch directory");           
File filePath = new File(dirPath, "Puzzle.txt");

try {
    if (!dirPath.exists()) {
        dirPath.mkdirs();
    }
    Writer writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(filePath), StandardCharsets.UTF_8));
    writer.write(savePuzzle.toString());
    writer.write("\n"); // or writer.newLine()
    writer.close();
} catch (IOException e) {
    e.printStackTrace();
}
