How to implement route cipher using java?

Question

Hi guys,,,
I really got a headache solving how to implement route cipher using java lang,,i already got the concept but i really dont get how to implement it using java actually i want to make a presentation of how route cipher works using "adobe flash" but first i will implement it using java coz flash actionscripts are closer to java lang.
Hope you could post some examples or ideas...i would really appreciate it!

Answer 1

just add an action listener (either keypressed or keytyped) to the frame that you want to record. I did this in NetBeans in about 2 seconds. I can simplify it if you need. As for loging it just write the characters to a file output stream.
public class test extends javax.swing.JFrame {
    /** Creates new form test */
    public test() {
        initComponents();
    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.
    // <editor-fold defaultstate="collapsed" desc=" Generated Code ">
    private void initComponents() {
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        addKeyListener(new java.awt.event.KeyAdapter() {
            public void keyTyped(java.awt.event.KeyEvent evt) {
                formKeyTyped(evt);
        pack();
    // </editor-fold>
    private void formKeyTyped(java.awt.event.KeyEvent evt) {
        System.out.println(evt.getKeyChar());
     * @param args the command line arguments
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new test().setVisible(true);
    // Variables declaration - do not modify
    // End of variables declaration
}
