Anyways im just confused on how to code the last two "else if" codings down there. Can anyone help me on that? Did i also code everything correctly? thanks in advance. Here is my code:
import java.applet.*;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class Lab7 extends JApplet implements ActionListener {
JLabel inputLabel;
//(0.5 pt) Create a label for outputLabel
JLabel outputLabel;
JTextField inputTxtFd;
//(0.5 pt) Create a text field for outputTxtFd
JTextField outputTxtFd;
JButton enableBnt;
// (1 pt)Create a button for disableBnt
// Create a button for clearBnt
JButton disableBnt;
JButton clearBnt;
JPanel dataPanel;
// (0.5 pt) Create a panel for buttonPanel
JPanel buttonPanel;
boolean echoEnabled;
public void init() {
dataPanel = new JPanel();
inputLabel = new JLabel("Type your input");
inputTxtFd = new JTextField(20);
// (1 pt) Create the output label, outputLabel with value “Echo”
// Create the output text field, outputTxtFd with 20 space
outputLabel = new JLabel("Echo");
outputTxtFd = new JTextField(20);
outputTxtFd.setEnabled(false);
dataPanel.add(inputLabel);
dataPanel.add(inputTxtFd);
// (1 pt) Add the output label, outputLabel, to the dataPanel
// Add the output text field, outputTxtFd, to the dataPanel
inputTxtFd.setEnabled(false);
dataPanel.add(outputLabel);
dataPanel.add(outputTxtFd);
// (0.5 pt) Create button panel, named buttonPanel;
// see code for creating data panel
JPanel buttonPanel = new JPanel();
enableBnt= new JButton("Enable");
//(1 pt) Create the disable button, disableBnt with value “Disable”
// Create the clear button, clearBnt with value “Clear”
disableBnt = new JButton("Disable");
clearBnt = new JButton("Clear");
buttonPanel.add(enableBnt);
// (1 pt) Add the disable button, disableBnt, to the buttonPanel
// Add the clear button, clearBnt, to the buttonPanel
buttonPanel.add(disableBnt);
buttonPanel.add(clearBnt);
getContentPane().add(dataPanel, BorderLayout.NORTH);
// (0.5 pt) Add the button panel to the applet, at SOUTH
getContentPane().add(buttonPanel, BorderLayout.SOUTH);
enableBnt.addActionListener(this);
// (1 pt) Listen to the disableBnt
// Listen to the clearBnt
disableBnt.addActionListener(this);
clearBnt.addActionListener(this);
inputTxtFd.addKeyListener(new KeyEventHandler());
}
public void start() {
clearBnt.setEnabled(false);
enableBnt.setEnabled(false);
echoEnabled= true;
inputTxtFd.setText("");
outputTxtFd.setText("");
}
class KeyEventHandler extends KeyAdapter {
public void keyReleased(KeyEvent evt) {
if(echoEnabled) {
outputTxtFd.setText(inputTxtFd.getText());
clearBnt.setEnabled(true);
}
}
}
public void actionPerformed(ActionEvent event) {
Object sourceObject = event.getSource();
if (sourceObject == enableBnt) {
echoEnabled = true;
enableBnt.setEnabled(false);
disableBnt.setEnabled(true);
}
else if (
//(0.5 pt) disable button is clicked) {
// (0.5 pt) fill in code
}
else if (//(0.5 pt)clear button is clicked) {
// (0.5 pt) clear the text fields
// (0.5 pt) disable the Clear button
}
}
