$1.$ Use IDEA to open the Kotlin$\_$OOP project that we worked on in class. If you code does not run, you can download my version from Modules.

$2.$ Create a new class called Mouse that extends the Animal class. $(20$ pts$)$

$3.$ The mouse is named "Jerry". Jerry does make sounds, it squeaks. Modify the code accordingly. $(30$ pts$)$

$4.$ Jerry is not like other animals. Jerry likes to store cheese. Create a private global integer variable for Jerry, named "CheeseAmount", set it by default to $0.$ Then, create a function "StealCheese" that increments the CheeseAmount by an integer x $($where x is an argument$),$ and a function "EatCheese" that decrements CheeseAmount by $1.(40$ pts$)$

$5.$ Create a new GitHub repository named Kotlin$-$OOP and upload your code. $($Make sure the repository is public, otherwise I cannot see it and thus cannot correct it$).(10$ pts$)$

$6.$ Submit the final URL in this Activity.
