Question

In java,

create a class named Contacts that has fields for a person’s name, phone number and email address. The class should have a no-arg constructor and a constructor that takes in all fields, appropriate setter and getter methods.

Then write a program that creates at least five Contact objects and stores them in an ArrayList. In the program create a method, that will display each object in the ArrayList. Call the method to demonstrate that it works.

Include javadoc comments for methods.

thank you!

public class Main {
