Comp 170 Lab 2 - Adding to the Notebook         Sept 17, 2007

Goals

Overview

For this lab you are to take the "stub" Club project -- dealing with club membership records -- and add some features. The club project is zipped here; save it and open it. I've added a few things that are not in the version from the book. You are to extend the constructor in class Membership, and add the methods indicated below to class Club.

The Constructor

The existing constructor for Membership has parameters for name, month, and year. I've added a field donations to this class; create a second constructor with parameters for name, month, year, and donations. Do not delete or change the existing constructor.

Methods / Loops

You are to provide the following methods to do the indicated things:

1. join(Membership member): This will add member to the list members.

2. listMembers(): This will be a loop to print all the members.

3. search(String s): Prints all members whose name contain the given string s as a substring. To check if s is contained in a member, use the library contains() method as follows:
        Membership member = members.get(N);
        if ( member.getName().contains(s)  ) {
            // print member
        }

4. totalDonations(): Returns (not prints) the total of the donations of all the members. You will need a temporary variable such as sum.

5. earliestMember(): Prints the member who joined earliest. It is acceptable to print the member with the smallest year of joining. 

    int minYear = 3000;			// initialize to a value >= any valid year
    int position = 0;
    Membership m = members.get(N);
    if (m.getYear() < minYear) {    // earliest year found so far
        position = N;
    }
After the completion of the loop, you print out members.get(position), the note with the given position.

For one point of extra credit, get this to work for the minimum (year, month) combination: have the loop return the member with the minimum joining date. You will need two variables: minYear and now minMonth, and the test for whether member m is earlier now becomes
    if (m.getYear() < minYear || (m.getYear() == minYear && m.getMonth() < minMonth) )

Email me your completed project. To create a zipfile out of a folder, navigate to the folder in the Windows Explorer (that is, not in BlueJ), right-click on the folder, and select Send To => Compressed (zipped) folder. This should create an ordinary file named <foldername>.zip. Then attach that zipfile to an email to me.
