Suppose you have a pre-existing class Pokemon that represents characters in a game, The class has the following data and behavior. Your task is to modify the class to be Comparable by adding an appropriate compare To method. All defensive Pokemon are considered to be "less than" aggressive Pokemon An defensive Pokemon is considered to be "less than" another if it has a lower defense power An aggressive Pokemon is considered to be "less than' another if it has a lower sum of attack and defense power. If two Pokemon are both aggressive or defensive and have the same defense or attack + defense power, they are considered to be "equal " Your method should not modify any Pokemon object's state. You may assume the parameter passed is not null.
