Java 干净的字符串？

Question

所以我正在使用 TCP，并从 DataInputStream 获取数据，但是当我获取数据时，它周围有 ^X^@^E^R 之类的内容。当它不应该做的时候。无论如何我可以删除这个吗？但它需要是动态的。

DataInputStream dataIn = new DataInputStream(socket.getInputStream());

StringBuffer inputLine = new StringBuffer();
String tmp;

while((tmp = dataIn.readLine()) != null){
    //tmp = Normalizer.normalize(tmp, Normalizer.Form.NFD);

    inputLine.append(tmp);
    logText(tmp);
}

Answer 1

DataInputStream.readLine() 已弃用。请改用 BufferedReader。

例如: BufferedReader input = new BufferedReader(new InputStreamReader(socket.getInputStream()));

我如何阅读行:

while ((socket != null) && !(socket.isClosed())) {
    // read in a line but only if there is one - blocks here till there is a line

    String clientSentence = input.readLine();

    if ((clientSentence != null) && (!(clientSentence.equals("")))) {
         // do something
    }
}
