Mar 22, 2011 · The most OOP suggestion I can give you is to create a class for every item/piece of information. For example: public abstract class ContactInfo { /* ... */ } public class Address extends ContactInfo { /* ... */ } public class PhoneNumber extends ContactInfo { /* ... */ } public class EmailAddress extends ContactInfo { /* ... */ } public class ...

Dec 3, 2011 · The use of objects will greatly help you here: class ADdressBook { List<Contact> contacts; function addContact(Contact contact) { contacts.add(contact); } } You will want to use …

Please implement an address book that allows a user to store (between successive runs of the program) the name and phone numbers of their friends, with the following functionality:

Feb 10, 2014 · You have the pieces in place you just need to put them together. First, think about the List being used. It is supposed to hold both types of contacts, however its type argument is using the derived type PersonalContact. Instead use the base class Contact List<Contact> contacts = new ArrayList<Contact>();

Oct 11, 2024 · It introduces core programming concepts like data structures, user input handling, and file I/O. In this blog post, we’ll walk through building a simple address book application that allows users to add, view, and delete contacts.

Implement the class and write some code in the main method to check if your code is correct. To get a feeling of the speed of a method it is often a good idea to count how many statements are executed for a given input. How many statements are executed in this code we have written:

A Java console application that manages an address book where the contacts are saved within an archive.

This page is the starting point into a series of pages that attempt to give a complete example of object-oriented analysis, design, and programming applied to a small size problem: a simple address book. These pages are similar in style to another, more complicated set of pages I developed earlier: A Simulation of an Automated Teller Machine (ATM).
