Java-读取文本文件时忽略某些字符
Java - ignoring certain characters while reading a text file

看起来您正在读取RTF文件，不是这样吗？

否则，我发现使用此构造对我来说阅读文本文件是最自然的：

        BufferedReader reader = new BufferedReader(
                                    new FileReader(new File("yourfile.txt")
                                );
        String text = null;

        // repeat until all lines is read
        while ((text = reader.readLine()) != null) {
            // do whatever with the text line
        }

因为这是一个RTF文件，所以请查看以下示例： RTFEditorKit

如果您坚持要编写自己的RTF阅读器，则正确的方法是扩展FilterInputStream并在其实现中处理RTF元数据。

只需将以下代码添加到您的类中，然后使用path参数对其进行调用。 它返回所有行作为List对象

public List<String> readStudentsNoFromText(String path) throws IOException {
            List<String> result = new ArrayList<String>();

            // Open the file that is the first
            // command line parameter
            FileInputStream fstream = new FileInputStream(new File(path));
            // Get the object of DataInputStream
            DataInputStream in = new DataInputStream(fstream);
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            String strLine;
            //Read File Line By Line
            while ((strLine = br.readLine()) != null) {
                // Print the content on the console
                System.out.println(strLine);
                result.add(strLine.trim());

            }
            //Close the input stream
            in.close();

            return result;
        }
