是否将java版本结果追加到上面的行？

import java.io.*;

public class AppendResult {
    public static void main(String[] args) {
        String filePath = "path/to/file.txt"; // 文件路径
        int lineNumber = 5; // 要追加的行号
        String result = "Java版本的结果"; // 要追加的结果

        try {
            File file = new File(filePath);
            BufferedReader reader = new BufferedReader(new FileReader(file));
            String line;
            StringBuilder content = new StringBuilder();

            int currentLine = 1;
            while ((line = reader.readLine()) != null) {
                if (currentLine == lineNumber) {
                    content.append(result).append("\n");
                }
                content.append(line).append("\n");
                currentLine++;
            }
            reader.close();

            BufferedWriter writer = new BufferedWriter(new FileWriter(file));
            writer.write(content.toString());
            writer.close();

            System.out.println("结果已成功追加到指定行。");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
