Question

i have this code .. but i want to build a java swing gui .. whichwill have a text box to input the password string and a gui spaceto display the output information

i am new to java gui.. can you create this sample gui for me ..when i understand this basic gui further changes to the gui as perrequirement i will do on my own. thanks

This isn't too difficult, as you may imagine: import java.awt.event.*; import java.awt.*; import javax.swing.*; import java.security.*; import javax.crypto.*; import javax.crypto.spec.*; import java.io.*; public class AESGUI extends JPanel {    public static void main(String[] args) {        JFrame frame = newJFrame("AES Encryption");        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);        frame.setPreferredSize(newDimension(600,300));        frame.setLocationRelativeTo(null);        frame.setResizable(false);               AESGUI p = new AESGUI();               frame.getContentPane().add(p);        frame.pack();        frame.setVisible(true);    }       private JTextField in;    private JTextArea out;       public AESGUI() {        JLabel info = newJLabel("Type any String");        in = new JTextField(20);        JButton encrypt = newJButton("Encrypt");        out = newJTextArea(10,40);               out.setEditable(false);               encrypt.addActionListener(newencryptListener());        in.addActionListener(newencryptListener());               add(info);        add(in);        add(encrypt);        add(out);        add(newJScrollPane(out));    }       private class encryptListener implementsActionListener {        public voidactionPerformed(ActionEvent e) {            Stringdata = in.getText();            if(data.length() == 0) { }            else               try {                   String en =encrypt(data);                   out.append("Encryptedstring: " + en + " ");                   out.append("OriginalString: " + decrypt(en) + " ");               } catch(Exception ex) { }        }    }       public String asHex(byte[] buf) {        StringBuffer strbuf = newStringBuffer(buf.length * 2);        int i;        for (i = 0; i
