Exercise : Introduction to OOP Concept

1.         Given the following incomplete code:

Draw a UML class diagram representing the code.

House

-houseType : String -houseAddress : String -housenoOfRooms : int -housePrice : double

+ setPrice(double): void  + getAddress() :String + calculateMonthlyPayment(int): double

2.         Based on the following scenario, answer the following questions:

 

You are appointed to develop a program for Philipsi Pressure Cooker company. The program should keep information about the pressure cooker which includes String for model (e.g. HD2139, RL1198, BF2222, EPC-6000s), char for size (e.g. L (large), M (medium), S (small)), String for colour (brown, silver, golden, white) and double for price (e.g. RM309.00, RM169.00, RM399.00, RM270.48). There will be a method in the PressureCooker class, named calculatePrice(). This method receives ONE (1) parameter: an int type variable named quantity. The method returns price, which is of type double. For this purpose, a class named PressureCooker has to be defined.

 

a)     Draw a UML class diagram for PressureCooker class.

PressureCooker

-pressureCookerModel: String -pressureCookerSize: char -pressureCookerColour: String -pressureCookerPrice: double

+CalculatePrice(int) : double

a)     Write a Java program for PressureCooker class.

 

public class PressureCooker {   private String model;   private String colour;   private char size;   private double price;   public double calculatePrice (int quantity)   {    Return price * quantity;   } }//end of PressureCooker class
