Java终端/CMD交互



我想做的是让我自己的java程序与pianobarfly交互(https://github.com/nega0/pianobarfly)通过命令行/终端。在这一点上,我似乎可以启动应用程序,但只有第一行是通过java打印出来的。它似乎没有意识到接下来的界线。我该怎么做?

    import java.io.*;
class mainA
{
    public static void main (String[] args) throws java.lang.Exception
    {
       try {
           Process p = new ProcessBuilder("/Users/sbuck1994/Desktop/pianobarfly-master/pianobarfly").start();
           BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
           BufferedWriter output = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
           String resultLine = input.readLine();
           while (resultLine != null) {
             System.out.println(resultLine);
             resultLine = input.readLine();
           }
           int exitVal = p.waitFor();
           System.out.println("Exited with error code "+exitVal);
       } catch(Exception e) {
           System.out.println(e.toString());
           e.printStackTrace();
       }
    }
}

这导致:

Welcome to pianobarfly (2012.09.07-dev)! Press ? for a list of commands.

当我认为它应该打印这样的东西时:
