I am taking a distance learning class on JAVA. I am stuck with the
following.  My code appears to work correclty, until it comes to the
DataInputStream. I am unable to figure out how to print the stream to my
console. I am reading a simple txt file of words (one per line). The Problem
could also be in the DataOutputStream, but I think I got that part correct.
Any help would be most appriciated.

import java.util.*;

import java.io.*;

public class PipeDemo{

public static void main(String args[]){

try{

PipedOutputStream out = new PipedOutputStream();

PipedInputStream in = new PipedInputStream(out);

Producer prod = new Producer(out);

Consumer cons = new Consumer(in);

prod.start();

cons.start();

}

catch (IOException e){System.out.println("Error: " + e);}

}

}

class Producer extends Thread{

private DataOutputStream out;

public Producer(OutputStream os){

out = new DataOutputStream(os);

}

public void run(){

try{

FileInputStream inputFile = new FileInputStream( "words.txt" );

InputStreamReader in = new InputStreamReader( inputFile );

BufferedReader br = new BufferedReader(in);

String input;

while ((input = br.readLine()) != null){

out.writeChars(input);

}

br.close();

}

catch(Exception e){System.out.println("Error: " + e);}

}

}

class Consumer extends Thread{

private DataInputStream in;

public Consumer(InputStream is)

{

in = new DataInputStream(is);

}

public void run(){

System.out.println(in.readLine);

}

}
