Question

Download and import the attached file Homework1Q1.zip to your Eclipse workspace (Click File > Import > General > Existing Projects into workspace > Select archive file). You will see one runner class in the default package that has errors. Fix the errors by creating the corresponding missing classes without modifying Runner.java. Once done, the output of your program should look exactly like the following:

ID Name   Age    CPD    Type

-----------------------------------------------------------------------------------------

1   Calvin   5    960 Elephant

2    Fluffy    4    320 Tiger

Setting number of meals per day of Fluffy to 2

2    Fluffy    4    640 Tiger

Setting number of meals per day to 30! Error, animals cannot eat more than 3 meals per day!

2    Fluffy    4    640   Tiger

Setting Fluffy's age to 8

2    Fluffy    4    640   Tiger

Printing All Animals:

ID   Name   Age   CPD   Type

---------------------------------------------------------------------------------------

1   Calvin    5 960    Elephant

2    Fluffy    8    640   Tiger

Total number of animals is: 2
