EDIT THE FOLLOWING CODE IN JAVA TO INCLUDE THE FOLLOWING

PART A: Add a method void animSort() that sorts the animals in the animals array based on their energy. You must use the Arrays.sort method in your implementation. For example, suppose that

animals = [Cow1, Chicken1, Llama1, null, null, ..., null] and assume that the order based on the energy is Llama1 < Chicken1 < Cow1. Then, animSort would change animals to:

animals = [Llama1, Chicken1, Cow1, null, null, ..., null]

PART B: Implement any changes outside the Farm class in order for animSort() to work properly.

PART C: Add a method boolean addClone(Animal anim) that clones the given animal, anim, and adds it to the animals array. For example, if animals has 4 animals and we call myFarm.addClone(animals[2]), a clone of animals[2] would be created and added to animals at the next available spot. The method addClone returns true if the animal is added successfully to animals and false if the farm is full.

PART D: Implement any changes outside the Farm class in order for addClone to work properly.
