[Note: In week 8 or 9 you can expect a quiz with some collection problem where you will be asked to design and code (into a textbox, NOT in Blue)!) a class and its methods somewhat similar to RollBook example below.] Use Blue) to design, code and test two classes to model a solution to the following problem. HINT: the problem is one class that contains as an instance variable a "Collection of instances of another class. A RollBook contains zero or more instances of Student such as "Doe. John" or "Brown, Sally" Each Student has a name as a single string in format shown above ("Last, First") Each Student has a street address [omitted in this lab) and a zipCode as a 5-character String A Student also has a gpa which is a decimal number in the range 0.0 to 4.0 1. Code class Student sufficient to model the above problem. -- Hint: instance variables, a constructor with two parameters, and two accessor methods. 2. Code class RollBook with custom methods to void add Student(String name, String zip, double gpa) //adds to collection Compute the average gpa of all students -- returns value as a decimal number (we did this one in class 7A] Count the number of students Hint: pay close attention to return type needed for with gpa higher than some each method below parameter value [e-g.. 3.2 Hint: read carefully to design an appropriate method value counts all students with name (no spces!) and the necessary parameter(s) gpa greater than or equal to needed for each method 3.2] - returns count Determine if a student with a particular name (or part of a name) is in the class - returns true or false. [Example: is "Brown," in the class?] LIST (output to screen) the names and gpa's of all students who live in a given zipCode (passed as a parameter) -- void method public void listByZipCode(String zip) TESTING: create an instance of RollBook, add test data, and invoke all your methods to verify that they are working as expected! Deliverable: Zip of your Blue) project folder, plus Word doc with screen shots and comments documenting your development and testing. In submission textbox, be sure to note any known defects
