Description
1.1 Given the following superclass named Food and subclass named WesternFood.
a) Complete the above classes by considering the following methods:
i. Write the default and normal constructor methods.
ii. Write the mutator methods for each attribute.
iii. The accessor methods for each attribute
iv. Write the printer method to return object information.
v. Write the processor methods named Payment() which calculates and returns the
amount to be paid by the customer based on the following table:
Set Set Description Amount (RM)
1 Lamb Chop 30.00
2 Chicken Chop 20.00
3 Fish and Chip 15.00
Super Class : Food
Attributes : String name; // customer’s name
int quantityOfOrder; //quantity order made
boolean member; //true – if member, otherwise
//false
Methods : Constructor, mutator, retriever, printer
Sub Class : WesternFood
Attributes : int foodSet; //1- lamb chop, 2- chicken
//chop, 3 – fish and chip
boolean desert; //true – if wants banana
//pie, otherwise false
Methods : Constructor, mutator, retriever, processor, printer
The customers need to pay extra RM 10.90 if they want the set that comes with dessert.
Besides, 10% discount will be given to the members.
b) Write a Java application which uses the concept of inheritance to:
i. Store data into an array of objects. The number of data to be stored and information
on each of the customers is given by the user.
ii. Display the details of customer’s information, including the payment.
iii. Count and display the number of customers who make a desert order.
iv. Calculate and display the total amount from the member’s customers.
v. Calculate and display the total amount of charges for all customers.
vi. Display the details of customer’s information who make an order the Lamb Chop set.

will be given if the number of paintings more than five (5).

a) Complete the above classes by considering the following methods:
i. Write the default and normal constructor for class.
ii. Write the mutator for each class
iii. Write the accessor for each class
iv. Write the printer for each class to return object information
v. Write a method named payArtist() for each subclass to calculate and return the
total payment paid to customers.
b) Write a Java application program for each of the following question:
i. Declare an array of object to store FIFTY (50) data on various types of artists and store
data onto the object.
ii. Display the details of Performer objects from the Rock genre which receives
payment for more than RM 10000.00
iii. Display the details of Painter objects which sold more than 10 painting.
