Create a program with classes and objects to provide greater flexibility, modularity, and reusability for developing Java applications: Java programing Assignment, UNIKL, Malaysia

Course Outcome to achieve:

CLO 2 — Create a program with classes and objects to provide greater flexibility, modularity, and reusability for developing Java applications

Objective: At the end of the session, students will be able to

• Implement advanced class features; Abstract class, Interfaces
• Differentiate the use of different access modifier

Complete the following steps:

1. Create the Pet Interface. The Pet Interface must satisfy the LAIL diagram above
2. Create the Animal class. The Animal class must satisfy the UML diagram above.

•  Declare a protected integer Instance variable called legs which records the number of legS for this animal
•  Define a protected constructor that initializes the legs instance variable (use this operator)
• Declare an abstract method Eat()
• Declare a concrete method Walk() that prints out something about how the animals walk (including the number of legs)

3. Create the Spider class

• Define a no-argument constructor that calls the superclass constructor to specify that all spiders have eight legs
• Override the Eat method (write a description of how and what spiders eat)

4. Create the Cat class

• This class must Include a String instance variable to store the name of the pet
• Define a constructor that takes one String parameter that specifies the cat’s name. This constructor must also call the superclass constructor to specify that all cats have four legs
• Implement the Pet interface methods
• Override the Eat method (write a description of how and what cats eat)
• Override the Walk method (write description on how catwalk include numbers of leg) • Override the Play method (write description on how to cat play)

5. Create the HelloPet class

• This class must include a String instance variable to store the name of the pet (virtual pet)
• Implement the Pet interface methods
• Override the Play method (write description on how to play with virtual pet)

6. Create the Test class

• Add the main method to create and manipulate instances of the classes that you have created previously
