[solved]-B Inheritance Overriding Animals Need Energy Move Get Energy Eating Food Moving Consumes E Q39018690
Please provide Javadoc. Thank you.
B – Inheritance and Overriding Animals need energy to move. They get energy from eating food while moving consumes energy. Create a class Animal with a constructor that takes no parameters and has an instance variable: private int energy; When an animal is “born,” it has one unit of energy. It has the methods • public void eat(int amountToEat) – which increases the amount of energy the animal has by amountToEat public void move(int amountToMove) – which decreases the energy the animal has by amountToMove. • public int getEnergy() – which returns the amount of energy left Notice there is no setEnergy method. Energy is only changed by eating or moving. Since it isn’t realistic for animals to be able to gather infinite amounts of energy, to have negative energy or to eat or move a negative amount, you should create a subclass BetterAnimal which has a cap on the amount of energy an animal can have. • The constructor takes a parameter that specifies a maximum for energy. You will need to save this in another instance variable. Override the eat and move methods In the eat method: If the amount the BetterAnimal eats would set its energy above the max, the energy level is only increased to the max. Also energy is only changed if the amount > 0 In the move method: Energy changes only if amount > 0. The energy can never be less than 0. If an BetterAnimal has an energy of 2 and tries to move 5, its energy will be 0. Provide Javadoc and submit both file to this CodeCheck link.
