Create a Java project that demonstrates various object oriented concepts you have learned so far
in this course (encapsulation, inheritance and polymorphism). To do this, create a super class and
at least 2 subclasses. You can either do multilevel inheritance or hierarchical inheritance in this
to complete this part-2 task.
The super class will have following properties/functionalities:
a) Create a total of 3 member variables for the class, selecting the appropriate data types
for each field.
b) Include an argument constructor in this Class, that will initialize all data fields.
c) Encapsulate this Class.
The two subclasses will have below properties/functionalities:
a) One of the subclasses will have at least one member variable and other subclass with at
least two member variables.
b) Have two constructors in each subclass:
• One constructor for initializing only super class data
• Another constructor will initialize both super and subclass data.
c) Encapsulate the subclasses.
d) You should include overloaded methods in any of the classes you have created
(superclass or subclass).
e) Override the toString( ) method in each of your Classes.
f) Override the equals( ) method in each of your Classes.
The test class [with the main ( ) method] will perform below tasks:
a) Create objects of superclass and each subclass types invoking all constructors and Draw
the object diagram for each of the object created.
b) Use setter methods to fill missing data in all objects.
c) Generate outputs demonstrating overloading, overriding outputs.
d) Create object of subclass [actual type] and store it in superclass object [declared type].
e) Generate output for instanceof operator.
f) Do object casting (show both implicit and explicit)
g) Generate output for constructor chaining [using this and super keywords]
Note:
1) Draw object diagrams wherever possible and necessary to show the state of the objects
created
Include the below in your project report:
• The UML diagram of all Classes.
• Screenshots of all output generated from the application.
