Question

A useful GUI. If you have the 10th edition of the Liang text, he deos a good job of describing JavaFX. If you have the 9th ed., he describes using Swing.   For the following exercise you can use either Swing or JavaFX.

Give me a clear indication of which you are using. DO NOT use/mix both.

Create an application that has a button that has “Enter your info.” When clicked it will present a dialog that has labels and text boxes that allow the user to enter their name, email, and phone number. The dialog will have buttons OK and Cancel.

When the user clicks Cancel, the dialog will go away without doing anything else.

When the user clicks OK, the user’s information will be extracted from the dialog, and dumped out on the console.

Notice that you only are listening for Click events.

Person.java

package com;

public class Person {

   private String Name;
   private String Email;
   private long PhoneNumber;

   Person(String name, String email, long phonenumber)
   {
       Name = name;
       Email = email;
       PhoneNumber = phonenumber;
   }
   public String getName() {
       return Name;
   }
   public void setName(String name) {
       Name = name;
   }
   public String getEmail() {
       return Email;
   }
   public void setEmail(String email) {
       Email = email;
   }
   public long getPhoneNumber() {
       return PhoneNumber;
   }
   public void setPhoneNumber(long phoneNumber) {
       PhoneNumber = phoneNumber;
   }

   @Override
   public String toString() {
       // TODO Auto-generated method stub
       return "Name=" + Name + " Email=" + Email + " PhoneNumber=" + PhoneNumber;
   }
}

               String name = JOptionPane.showInputDialog("Enter Name: ");
               String email = JOptionPane.showInputDialog("Enter email: ");
               long number = 0;
               number = Long.valueOf(JOptionPane.showInputDialog("Enter phone number: "));
               if(name != null && email != null && number != 0)

               System.out.println(" Sorted List: ");
               for(int i=0; i<listOfPersons.size(); i++)
               {
                   System.out.println(listOfPersons.get(i));
               }
           }
        
       });
       frame.getContentPane().setLayout(new FlowLayout());
       frame.getContentPane().add(enterInfo);
       frame.getContentPane().add(sort);
       frame.setSize(500, 500);
       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
       frame.setVisible(true);
   }

   public static void main(String args[])
   {
       new PersonGUI();
