Thread: Console box with scanner?

So I found this really cool code here:

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.text.*;
 
public class Console extends JFrame {
    PipedInputStream piOut;
    PipedInputStream piErr;
    PipedOutputStream poOut;
    PipedOutputStream poErr;
    JTextArea textArea = new JTextArea();
 
    public Console() throws IOException {
        // Set up System.out
        piOut = new PipedInputStream();
        poOut = new PipedOutputStream(piOut);
        System.setOut(new PrintStream(poOut, true));
 
        // Set up System.err
        piErr = new PipedInputStream();
        poErr = new PipedOutputStream(piErr);
        System.setErr(new PrintStream(poErr, true));
 
        // Add a scrolling text area
        textArea.setEditable(false);
        textArea.setRows(20);
        textArea.setColumns(50);
        getContentPane().add(new JScrollPane(textArea), BorderLayout.CENTER);
        pack();
        setVisible(true);
 
        // Create reader threads
        new ReaderThread(piOut).start();
        new ReaderThread(piErr).start();
    }
 
    class ReaderThread extends Thread {
        PipedInputStream pi;
 
        ReaderThread(PipedInputStream pi) {
            this.pi = pi;
        }
 
        public void run() {
            final byte[] buf = new byte[1024];
            try {
                while (true) {
                    final int len = pi.read(buf);
                    if (len == -1) {
                        break;
                    }
                    SwingUtilities.invokeLater(new Runnable() {
                        public void run() {
                            textArea.append(new String(buf, 0, len));
 
                            // Make sure the last line is always visible
                            textArea.setCaretPosition(textArea.getDocument().getLength());
 
                            // Keep the text area down to a certain character size
                            int idealSize = 1000;
                            int maxExcess = 500;
                            int excess = textArea.getDocument().getLength() - idealSize;
                            if (excess >= maxExcess) {
                                textArea.replaceRange("", 0, excess);
                            }
                        }
                    });
                }
            } catch (IOException e) {
            }
        }
    }
}

This code basically makes my program display in a console box from what I can tell. I was wondering if anyone knows how to make it so it has a input like scanner too?
Maybe its too much to bother you guys for, but I really want to use this and I can't do it myself since I hardly understand what its doing heh..

But seriously any help would be awesome.
