Ghost Sitter

The Ghost Sitter program lets you have your very own ghost. The ghost only east candy and wants to be the spookiest Ghost around. The player drives the action by their choice. The play can inquire to how the ghost is feeling by speakWithTheSprits()

1.   File Ghost.java contains a partial definition for a class representing a ghost. Save it to your directory and study it to see what methods it contains. Then complete the Ghost class as described below.

1. Fill in the code for method getHunger(), which should return the hunger level as an integer.

2. Fill in the code for method eatCandy(), which should decrease the hunger level by 3 and set it to 0 if it is greater than 0. The hunger level will start at zero and grow towards negative infinity. (The ghost doesn't actually eat the candy, the player does.)

3. Fill in the code for method scare, which should decrease the spookieness level by 3 and set it to 0 if it is greater than 0. 4. Fill in the code for method speakWithTheSprits which prints the ghost's mood, which can be vengeful (if mood < -15), whistful (if mood < -10 and mood >= -15), spooky (if mood < -5 and mood >= -10), or friendly (if mood > -5).

2.   File GhostSitter.java contains a driver program that uses the Ghost class above. Save it to your directory and study it to see what it does. Then compile and run it to test the Ghost class. (Do not make any modifications to GhostSitter.java)
