JAVA Create a class named Customer that will determine the monthly repayment amount due by a customer for a product bought on credit. The class has five fields: customer name, contact number, product price, number of months and the monthly repayment amount. Write get and set methods for each field, except for the monthly repayment amount field. The set methods must prompt) the user to enter the values for the following fields: customer name, contact number, product price and number of months. This class also needs a method to calculate the monthly repayment amount (product price divided by the number of months). Add a subclass named Finance_Period that will determine if a customer pays interest or not. If the number of months to pay for the product is greater than three, the customer will pay 25% interest, else no interest applies. The maximum number of months to pay for the product is 12 months. Override the calculate_repayment () method by determining if the customer will pay interest or not and calculate the monthly repayment amount. Create a class called Customer_Finance that contains the logic to test the two classes. Prompt the user for data ((Use JOptionPane to receive the data) for the first object where no interest applies and display the results; then prompt the user for data where interest is applicable and display the results. Make use of Exception handling to ensure that the flow of the program doesn't break when an exception occurs. Before creating your program use any tool of your choice to create a program Structure (as shown in question 1) and also explain how you have applied the Object Oriented Principles (Polymorphism, Encapsulation, abstraction, and Inheritance) to showcase the flow of the program you are about to create.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
