从无限循环中读取流

Question

I'm trying out some socket programming in Java for a little project. I've ran into a problem reading an infinite InputStream from an external process. The program goes into an infinite loop.

I suspect that readLine() have to read the stream until EOF.

I've put some print statements and I'm sure that the program reaches the while-loop.

This is my method:

    public void run() throws IOException {
        Process p = Runtime.getRuntime() .exec(exe);

        BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String line;

        while((line = in.readLine()) != null){
            System.out.println(line);
            dout.writeUTF(" " + line + " yes!");
            dout.flush();
        }

        in.close();
        dout.close();
        s.close();
        ss.close();
    }

正如@codeflush.dev 提到的，流没有到达 EOF，因此 readLine 不是一个可行的选择。
