Question:

Write a Java application that implements different types of insurance policies for employees of an organization.

Let Insurance be an abstract superclass and Health and Life two of its subclasses that describe respectively health insurance and life insurance.

The Insurance class defines an instance variable of type String to describe the type of insurance and an instance variable of type double to hold the monthly cost of that insurance.

Implement the get methods for both variables of class Insurance. Declare also two abstract methods named setInsuranceCost() and displayInfo() for this class.

The Life and Health class should implement setInsuranceCost and display methods by setting the appropriate monthly fee and display the information for each insurance type.

Write a driver class to test this hierarchy. This application should ask the user to enter the type of insurance and its monthly fee. Then, will create the appropriate object (Life or Health) and display the insurance information.

As you create each insurance object, place an Insurance reference to each new Insurance object into an array. Each class has its own setInsuranceCost method. Write a polymorphic screen manager that walks through the array sending setInsuranceCost messages to each object in the array and displaying this information on the screen.

Exercise #2:

Create an abstract class called GameTester. The GameTester class includes a name for the game tester and a boolean value representing the status (full-time, part-time).

Include an abstract method to determine the salary, with full-time game testers getting a base salary of $3000 and part-time game testers getting $20 per hour.

Create two subclasses called FullTimeGameTester, PartTimeGameTester. Create a console application that demonstrates how to create objects of both subclasses. Allow the user to choose game tester type and enter the number of hours for the part-time testers.

Exercise #3:

CityToronto bank provides mortgages for individuals and businesses up to $300,000. Write a Java application that keeps track of mortgages and computes the total amount owed at any time (mortgage amount + interest).

Design the following classes to implement your application:

Mortgage - an abstract class that implements the MortgageConstants interface. A Mortgage includes a mortgage number, customer name, amount of mortgage, interest rate, and term.

Don't allow mortgage amounts over $300,000. Force any mortgage term that is not defined in the MortgageConstants interface to a short-term, one year loan. Create a getMortgageInfo method to display all the mortgage data.

MortgageConstants - includes constant values for short-term(one year), medium-term (three years) and long-term (5 years) mortgages. It also contains constants for bank name and the maximum mortgage amount.

BusinessMortgage - extends Mortgage. Its constructor sets the interest rate to 1% over the current prime rate.

PersonalMortgage - extends Mortgage. Its constructor sets the interest rate to 2% over the current prime rate.

ProcessMortgage - a main class that create an array of 3 mortgages. Prompt the user for the current interest rate. Then in a loop prompts the user for a mortgage type and all relevant information for that mortgage. Store the created Mortgage objects in the array. When data entry is complete, display all mortgages.
