Java扫描仪读取垃圾 [英] Java scanner reading garbage

问题描述

我正在使用Java扫描仪读取文本文件.

I am reading a text file using java Scanner.

try {
            while(sc.hasNextLine()) {
                //Read input from file
                inputLine = sc.nextLine().toUpperCase();
                System.out.println(inputLine);
}

以上给出了以下输出，而我的文本文件仅包含"aabbcc". 如何避免扫描仪扫描垃圾? 谢谢.

The above gives below output while my text file only includes "aabbcc". How to avoid scanner from scanning the garbage? Thanks.

推荐答案

您正在阅读RTF文档.如果您只想阅读文本，则可以尝试将其读取为字节数组，然后使用swings rtfeditorkit解析文本.

You are reading a RTF Document. If you want to read the text only you can try reading it into a byte array and parsing out the text using swings rtfeditorkit.

Path path = Paths.get("path/to/file");
byte[] data = Files.readAllBytes(path);

RTFEditorKit rtfParser = new RTFEditorKit();
Document document = rtfParser.createDefaultDocument();
rtfParser.read(new ByteArrayInputStream(data), document, 0);
String text = document.getText(0, document.getLength());
