No late submission is allowed.]

General Scenario:

You are creating an interactive application that gets input from the keyboard and keeps track of the records of students of Centennial College. In order to develop this application, you will be using an abstract class and use that class to create a concrete class. Your application should have overridden toString() at appropriate places so that you could display the object state, i.e., the string representation of the objects that you created by simply using the following command: System.out.println(object).

Follow the following instructions:

Create an abstract class named Student. This class contains three instance variables, one constructor, and three abstract methods.

Instance variables: studentId, name, and address (Use appropriate data type.)

Constructor: one constructor that would help constructing an object in its subclass with all the student information including studentId and name.

Three abstract methods: getId, getName, and getAddress. Each of these methods, when sub classed into concrete ones, should return the respective values of the instance variables studentId, name, and address.

[25 marks]

Create a concrete class named CentStudent that makes use of the abstract class Student. This class has two instance variables of its own, one constructor, and two methods of its own.

Instance variables: dept and tutionFee. (Use appropriate data type).

Constructor: one constructor that constructs a CentStudent object with all the centStudent information (studentId, name, department, and tutionFee) supplied during the centStudent object creation.

Methods: getDept and getTuition that return the values of the two instance variables of this level individually.

Take necessary action to make this class a concrete class.

[35 marks]

Create a driver class named TestX (replace XXX by three letters of your last name) that would continuously ask for student Id, name, department, and tuition fees from the user and displays each record as you provide all the information about each of them. Make sure to use a loop that only stops when you enter -1 as an input when asked for student id. If you enter -1 at this point, the application should display particular information as shown in the test run below and quit by displaying a message also shown in the test run.

[40 marks]

Your test run should look like the following:
