Objective:

Write 2 user defined classes (including a class that contains a "main" method). These classes should be names "Driver" and "Band". The Driver class should contain the main method and will also contain methods to test your other classes.

Specifications:

Driver Class

Create a class called "Driver" with the "main" method. As you write the other classes, you will write methods in the Driver which test the classes. The test methods that you must write are outlined here. All methods in Driver should be public static.

Method name: testBandDefaultConstructor

Input: nothing

Return: nothing

Purpose: Instantiate a Band object and call the objects print method.

Method name: testBandNonDefaultConstructor

Input: int size

Return: nothing

Purpose: Instantiate a Band object with initial size given as an argument to this method and call the objects print method.

Method name: testBandAddMember

Input: nothing

Return: nothing

Purpose: Instantiate a default Band object and add members "Bob", "Susan", "Steve", and "Barb" to the array of band names. Call the objects print method.

Method name: testBandClearNames

Input: nothing

Return: nothing

Purpose: Instantiate a Band object and add members "Bob", "Susan", "Steve", and "Barb" to the array of band names. Call the objects print method. Call the objects clearNames method and then call the objects print method again.

Method name: testBandResize

Input: nothing

Return: nothing

Purpose: Instantiate a Band object of size 2. Add members "Bob" and "Susan". Call the objects print method. Now add "Steve" to the array of band names. Call the objects print method. Now add "Jessica", "Chuck", and "Darlene" to the band and call the objects print method again.

Method name: main

Input: String[] args

Output: void

Purpose: you should call your tester methods here. Remove all lines of code from the main method prior to submitting your code.

Band Class

Create a class called "Band" with the following fields, methods, and constructors.

Field name: names

Accessibility: private

Type: Array of Strings

Purpose: used to store the names of all of the band members.

Field name: memberCount

Accessibility: private

Type: int

Purpose: used to store the number of band members.

Method name: resizeNamesArray

Accessibility: private

Input: int memberCount

Output: void

Purpose: resize the names array so that it has size given as an argument to this function. If growing the array, the new array should contain all of the names from the existing array. If shrinking an array, the new array should contain as many of the names from the existing names array as possible.

Example 1: if names = {"Bob", "Susan", "Steve", "Barb"} and memberCount = 4, the call resizeNamesArray(6) results in names = {"Bob", "Susan", "Steve", "Barb", "", ""} and memberCount = 4. Note the extra spaces in the array containing empty strings.

Example 2: if names = {"Bob", "Susan", "Steve", "Barb"} and memberCount = 4, the call resizeNamesArray(2) results in names = {"Bob", "Susan"} and memberCount = 2. Note that two names have been removed.

Method name: addMember

Accessibility: public

Input: String name

Output: void

Purpose: add a band member to the array of band member names. Don't forget to increment your memberCount. If the names array is not big enough to add the new band member's name, it must be resized. Use the resizeNamesArray method to double the size of the array.

Method name: clearNames

Accessibility: public

Input: nothing

Output: nothing

Purpose: Resets your memberCount to 0.

Method name: print

Accessibility: public

Input: void

Output: void

Purpose: print the list of band members

Example 1: if names = {"Bob", "Susan", "Steve", "Barb","",""} and memberCount = 4, this method should display:

There are 4 band members. Bob Susan Steve Barb Band capacity is 6. 

Example 2: if memberCount = 0 and names.length = 6, this method should display:

The are 0 band members. Band capacity is 6. 

Default Constructor

Accessibility: public

Input: void

Purpose: initialize the names array and the memberCount. By default, you can assume that a band has 10 or fewer band members. memberCount should be initialized to 0.

Non-default Constructor

Accessibility: public

Input: int size

Purpose: initialize the names array and the memberCount. The names array should be initialized with size given as the argument to the constructor. memberCount should be initialized to 0.
