Displaying the output from a java class executed from W/I another class

Question

I have compiled a java class, but I have run into a problem executing the class. I have read the posts and still have not solved the solution. I have tried to get the output of the Process by using "proc.getOutputStream().toString()", however it displays it in binary (ex. java.io.BufferOutputStream@48eb2067). If anyone can provide any assistance I would greatly appreciate it. Or if you could tell me if I'm on the right track or not. Thanks ALL. Here is a code segment:
int truncStart = s.indexOf(".java");
               s = s.substring(0,truncStart);
               String[] command2 = {"java","c:/"+s};
               try
               //JOptionPane.showMessageDialog(null,"Exec. File "+s, "Exec. File : ",JOptionPane.ERROR_MESSAGE);
               proc = Runtime.getRuntime().exec(command2);
               JOptionPane.showMessageDialog(null,"Output: "+proc.getOutputStream().toString(),"Output"
,JOptionPane.ERROR_MESSAGE);
               }

You have to read the stream, like:
InputStream stream = proc.getOutputStream();
// now use methods on stream, such as read() to read the characters/lines - or wrap it in another line-friendly stream - see the java.io.* classes - keep reading until you get an end-of-stream indicator, depending on the API you end up using.
