 + * A Food object is created with parameters that define the name of the food, 
 + * the increase in energy level, the increase in happiness level, 
 + * and the amount of weight gained if the food is consumed by a 
 + * VirtualPet object. 
 + * 
 + * The Food class provides a constructor with the following header: 
 + * public Food(String name, int energyIncrease, int happinessIncrease, int weightGain). 
 + * The Food class also has accessor methods for all instance variables.

 +==== Part C Putting it all together ====
  
 +Now that we have a Game and Food class, let’s revise the VirtualPet class to include interactions with these classes. 
 +  - Write the class VirtualPet4. You may copy your code implementation of VirtualPet from Activity 3 but be sure to modify the class header and constructor to match the new class name. 
 +
 +  - Modify the ''feed()'' method to take a ''Food'' parameter. The method should increase the ''energy'' level, ''happiness'' level, and ''weight'' of the virtual pet object based on the ''getEnergyRating()'', getHappinessRating(), and getWeightGain() accessor methods of the Food parameter. It is possible for the ''happiness level'' to decrease depending on the ''Food'' consumed. 
 +
 +  - Modify the ''play()'' method to take a ''Game'' parameter and return a ''boolean'' value indicating whether the game was won. The method should decrease the weight based on the ''getWeightLoss()'' accessor method of the ''Game'' parameter. Remember, the weight can not go below the minimum ''weight'' value. The method should also increase the ''happiness'' level only if the ''Game parameter’s'' accessor method ''isWinner()'' returns ''true''. The method should decrease the happiness level if isWinner() returns false. The method should return the same value returned by ''isWinner()''. (Note: Be sure to call ''isWinner()'' only once in the method. Repeated calls may result in different return values.)

 +===== Activity 5 =====
 +
 +==== Adding Your Own Features ====
 +Copy your code from ''Food.java'' and ''Game.java'' to your working project for Activity 5. Copy your code from ''VirtualPet4.java'' to a new file named ''VirtualPet5.java''. Be sure to modify your class header to match the name of your ''.java'' file.  
 +
 +Implement two new features in your ''VirtualPet5'' class or ''Game'' class. Your new features should add instance variables and/or methods to your ''VirtualPet5'' class. 
  
 +The following are ideas for additional features, inspired by the original Tamagotchi: 
 +  - Your virtual pet has a hidden health level based on their energy, happiness, sickness, and cleanliness.  
 +  - Your virtual pet will randomly use the bathroom and will need to be cleaned. 
 +  - Your virtual pet will randomly get sick and need to be given medicine. 
 +  - Your virtual pet will notify the user if their energy level is 0, if their happiness level is 0, if they are sick, or if they used the bathroom and need to be cleaned.  
 +  - Create a more interactive game in the Game class for the ''VirtualPet'' to play.
