Java Runtime.exec - can you read the output interactively?

Question

I am running a program never ends, its a text based download manager. It gives output on ONE line, and this isnt in std.out (im using unix).
this continues (basically it just gives you a view of how much progress the file is downloading.
Is there a way to read this from java?
cheers.

Answer 1

try
{   // Execute command
    String command = "aCommand";
    Process child =  Runtime.getRuntime().exec (command);
    // Get input stream to read from it
    InputStream in = child.getInputStream();
    int c;
    System.out.println("Command returns ");
    while ((c = in.read()) != -1)
        System.out.println("---"+((char)c));
    in.close();
catch (IOException e)
     System.out.println("Exception occurred: "+e);
}
