Purpose of this assignment:

To provide learners with an understanding of the principles of programming in Java, exploring the object oriented nature of the language and the multi-platform versatility offered.

Scenario:

Holiday Premiers Inc. is a new holiday business company. They are planning to design a program to manage the storage of data in the company. There are two types of holiday packages offered by the company, a Standard package and a Premium one. The Premium packages include some additional extras such as guided tour and accommodation with breakfast.

You were asked to design a software to manage their customers. The program should be able to do the following:

• Program should have minimum 2 classes and 2 functions (Inheritance and parameter passing technique should be demonstrated).

• Program should be able to read the information of customers (e.g. Name, Address, Date of Birth, Phone number, Holiday destination, and Total cost of the holiday, Deposit payment, and outstanding payment, etc.).

• Program should be able to display information of customers.

• Program should be able to accept deposit from customers and update their balance.

• Program should be able to calculate the total cost of the holiday.

• Program should be able to find specific customer name or holiday and update it (e.g. update the outstanding payment).

• Program should be able to accept any instalment paid for a certain holiday and update the remaining balance (outstanding payment) accordingly.

• Program should display error message if user enters invalid values for Date of Birth and deposit amount.

• The cost of the premium package includes a price of first class flight, hence this price should be included in the list of the Premium package.

• The total cost of the holiday packages are calculated as follows:

Standard package = (No. of days x cost per day)

Premium package = ((No. of days x cost per day) x 1.3) + Flight

Where cost per day, and flight cost differs according to destination.
