Re questing help with a two part assignment:

Questions:

Clock.java

/** * Store details of club memberships. * * @author (your name) * @version (a version number or a date) */ public class Club { // Define any necessary fields here ... /** * Constructor for objects of class Club */ public Club() { // Initialise any fields here ... }

/** * Add a new member to the club's list of members. * @param member The member object to be added. */ public void join(Membership member) { }

/** * @return The number of members (Membership objects) in * the club. */ public int numberOfMembers() { return 0; } }

Clock.java Ends

Membership.java

/** * Store details of a club membership. * * @author David J. Barnes and Michael Klling * @version 2016.02.29 */ public class Membership { // The name of the member. private String name; // The month in which the membership was taken out. private int month; // The year in which the membership was taken out. private int year;

tu surve a particular problem. g iem right can make it a lot easier Exercise 4.40 Use the club project to complete this and the following exercises. Your task is to complete the Club class, an outline of which has been provided in the project. The Club class is intended to store Membership objects in a collection. Within Club, define a field for an ArrayList. Use an appropriate import statement for this field, and think carefully about the element type of the list. In the constructor, create the collection object and assign it to the field. Make sure that all the files in the project compile before moving on to the next exercise. Exercise 4.41 Complete the numberOfMembers method to return the current size of the collection. Until you have a method to add objects to the collection, s return zero, of course, but it will be ready for further testing later. Exercise 4.42 Membership of a club is represented by an instance of the Membership class. A complete version of Membership is already provided for you in the club project, and it should not need any modification. An instance contains details of a person's name and the month and year in which they joined the club. All membership details are filled out when an instance is created. A new Membership object is added to a Club object's collection via the Club object's join method, which has the following description: Add a new member to the club's collection of members. * eparam member The member object to be added public void join (Hembership member) Complete the join method
