CSE1/CSE4IOO: Object-Oriented Manner - Inheritance in Java - File Input and Output in Java - Exception Handling - IT Assignment Help

Assignment Task:

Objectives:

The general aims of this assignment are: 
• To analyze a problem in an object-oriented manner, and then design and implement an object-oriented solution that conforms to given specifications 
• To practise using inheritance in Java 
• To practise file input and output in Java 
• To make implementations more robust through mechanisms such as exception handling. 

Task 1:

Design an inheritance hierarchy for the animals in the Rescue and Release Shelter. Draw a diagram to show the inheritance hierarchy. For simplicity, include the attributes only.

Task 2:

• Implement class Kangaroo (and of course, its superclass). 
• Run the test program KangarooTester in Appendix A. Your Kangaroo class must be such that the test program can be run without changes. 
• Note: You do not need to implement methods relating to filing input/output. These requirements will be done in Part 2 of the assignment.

Task 3:

• Implement class, Joey. 
• Run the test program JoeyTester in Appendix B. Your Joey class must be such that the test program can be run without changes.

Task 4:

• Implement class Possum. 
• Run the test program PossumTester in Appendix C. Your Possum class must be such that the test program can be run without changes.

Task 5:

• Implement class RRShelter, which maintains the collection of animals in the shelter. 
• The collection is maintained as an array. Assume that the maximum number of animals is 100. 
• This class must have at least methods to add and release animals. 
• Run test programs RRShelterTestAddAnimal and RRShelterTestReleaseAnimal in Appendices D and E, respectively. Your shelter must be such that these test programs can be run without changes.
