In the 1D Arrays Unit, i have created a command-line Contact Manager v1 which is given below. Now upgrade the software to include a graphic user interface.

//written by - Adil Mahmood //Sunday April 10 2022 /** * The Contact Manager Assignment class implements an application that demonstrates * Contact Manager Assignment */ import java.util.Scanner;

class Contact { // fields private String name; private String number;

// constructor public Contact(String name, String number) { this.name = name; this.number = number; }

// getters and setters public String getName() { return this.name; }

public void setName(String name) { this.name = name; }

public String getNumber() { return this.number; }

public void setNumber(String number) { this.number = number; } } public class ContactManager { // fields private Contact[] contacts; private int numContacts;

// constructor public ContactManager() { this.contacts = new Contact[100]; this.numContacts = 0; }

// methods // view all contacts public void viewAll() { for (int i = 0; i < numContacts; i++) { System.out.println("Name: " + contacts[i].getName()); System.out.println("Phone number: " + contacts[i].getNumber()); } }

// add a contact public void add(String name, String number) { contacts[numContacts] = new Contact(name, number); numContacts++; }

// modify a contact public void modify(String name, String number) { for (int i = 0; i < numContacts; i++) { if (contacts[i].getName().equals(name)) { contacts[i].setNumber(number); } } }

// delete a contact public void delete(String name) { for (int i = 0; i < numContacts; i++) { if (contacts[i].getName().equals(name)) { for (int j = i; j < numContacts - 1; j++) { contacts[j] = contacts[j + 1]; } numContacts--; } } }

public void printMenu() { System.out.println("1. View all contacts"); System.out.println("2. Add a contact"); System.out.println("3. Modify a contact"); System.out.println("4. Delete a contact"); System.out.println("5. Save book"); System.out.println("6. Load book"); System.out.println("7. Quit"); }

public static void main(String[] args) { ContactManager manager = new ContactManager(); Scanner in = new Scanner(System.in); String input; int choice;

do { manager.printMenu(); input = in.nextLine(); choice = Integer.parseInt(input);

if (choice == 1) { manager.viewAll(); } else if (choice == 2) { System.out.println("Enter name:"); input = in.nextLine(); String name = input; System.out.println("Enter number:"); input = in.nextLine(); String number = input; manager.add(name, number); } else if (choice == 3) { System.out.println("Enter name:"); input = in.nextLine(); String name = input; System.out.println("Enter number:"); input = in.nextLine(); String number = input; manager.modify(name, number); } else if (choice == 4) { System.out.println("Enter name:"); input = in.nextLine(); String name = input; manager.delete(name); } else if (choice == 5) { // save } else if (choice == 6) { // load } else if (choice == 7) { System.out.println("Quitting..."); } } while (choice != 7); }

}

Your contact manager must:

• Have a menu bar that provides access to the following functionality (it is up to you to organize):
  • Quitthe application
  • Savethe Contacts
  • Loadthe Contacts
  • Adda Contact
  • Deletea Contact
  • Edita Contact
  • Viewall entries in a table
  • Sortthe Contacts by a selected field
• Store the contacts in a 1D Contact array with at least the following fields:
  • First Name
  • Last Name
  • Address
  • Phone Number
  • E-Mail
• Use methods to incorporate a modular design.
• Use proper internal documentation as per the Java Coding Conventions.
• Include the executable JAR of your program.
