For this exercise, you will be given a project file digital_pet containing two (2) classes, the DigiPet class and the DigiPetTester class. Every DigiPet has five fields: - name - lifespan (in cycles) – max age - age (in cycles) – current age - mood (2 = joyful, 1 = happy, 0 = neutral, -1 = sad, -2 = angry) - size – current size of pet (size > 1) • A DigiPet has a default constructor, overloaded constructor, and some various methods which allow one to interact with it or modify its state. • Poke or pet increases or decreases its mood. • Feed or exercise increases or decreases its size by a specified amount. Every time you interact with the digipet (poke, pet, feed, exercise), its age increases. When the age reaches the lifespan, it dies (or becomes a zombie). You need to modify and customize the DigiPet class as follows: - Implement the overloaded constructor: Initialize all five fields. Use the new values (passed as parameters) along with the same default values that the default constructor uses. - Implement poke(): Decrement mood by 1. Check and make sure mood stays larger than or equal to -2. If it is less than -2, set mood to -2. Call the makeOlder() method to make the pet older by one cycle. (Note that the makeOlder() method is already implemented for you; you simply need to call it.) - Implement pet): Increment mood by 1. Check and make sure mood stays smaller than or equal to 2. If it is larger than 2, set mood to 2. Call the makeOlder() method to make the pet older by one cycle. - Implement feed(int amount): Increases the pet's size by the amount (passed as a parameter to the method). Call the makeOlder() method to make the pet older by one cycle. - Implement exercise(int amount): Decreases the pet's size by the amount. If the resulting size is smaller than 1, print a message "No more energy!" and set the size to 1. Call the makeOlder() method to make the pet older by one cycle. - Modify showPet() (optinal): Customize it any way you like but with the following requirements: It must show the name, age, and lifespan. It must depict the size and mood in some way (be creative).
