Question

Please design a Java GUI application with two JTextField for user to enter the first name and last name. Add two JButtons with action events so when user click on one button to generate a full name message from the user input and put it in a third JTextField which is not editable; and click on the other button to clear all three JTextField boxes. Please run the attached nameFrame.class file (Note: because there is an actionhandler inner class in this program, another class file nameFrame$actionhandler.class was generated when you compile the .java file, you need both files in the same directory in order to run) to see the sample output. You need to design your program with a similar look and have your name as the author in a JLabel.

public nameFrame(){

prepareGUI();

}

public static void main(String[] args){

nameFrame nameFrame = new nameFrame();

}

private void prepareGUI(){

mainFrame = new JFrame("Name Frame");

mainFrame.setSize(450,250);

mainFrame.setLayout(new GridLayout(5, 2));

 

mainFrame.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent windowEvent){

System.exit(0);

}

});  

JLabel fname= new JLabel("First Name : ");

JLabel lname = new JLabel("Last Name : ");

JLabel fullname = new JLabel("Full Name : ");

JTextField fnameText = new JTextField(15);

JTextField lnameText = new JTextField(15);

JTextField fullnameText = new JTextField(30);

fullnameText.setEditable(false);

JButton submit = new JButton("submit");

submit.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {  

String data = fnameText.getText() + " " + lnameText.getText();

fullnameText.setText(data);

}

});

JButton clear = new JButton("clear");

clear.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {  

fnameText.setText("");

lnameText.setText("");

fullnameText.setText("");

}

});

mainFrame.add(fname);

mainFrame.add(fnameText);

mainFrame.add(lname);  

mainFrame.add(lnameText);

mainFrame.add(fullname);  

mainFrame.add(fullnameText);

mainFrame.add(submit);

mainFrame.add(clear);

mainFrame.setVisible(true);
