1) Write a Java class to encapsulate the concept of a television set. The class should include:

• Private instance variables of channel, volume, and input mode (all as integers)
• A no-argument constructor to initialize instance variables to all zeros
• A constructor that initializes all variables to values passed in as arguments
• An accessor (i.e. getter) method for each instance variable
• A mutator (i.e. setter) method for each instance variable
• A toString method that will return the current state (i.e. values) of the instance variables as a string

2) Write a Java class to encapsulate the concept of a student. The class should include:

• Private instance variables of name (string), CWID (string), and GPA (double)
• A constant static variable called MINGPA that is set to 0.0
• A constructor to initialize the instance variables to values passed in as arguments
• A constructor to initialize the name and CWID using arguments passed into it, but uses MINGPA to initialize GPA
• An accessor method for each instance variable
• A mutator method for each instance variables
• An equals method that will compare an instantiated student object to another by compare all three attributes. This should return true if they match or false if they do not. (Hint: Refer to Review of Objects - Part 10).

3) Write a Java class to encapsulate the concept of a car. The class should include:

• Private instance variables of VIN (string), make (string), model (string), year (integer), and number of miles driven (double)
• A constructor to initialize the instance variables to values passed in as arguments
• An accessor method for each instance variable
• A mutator method for each instance variable
• An equals method that will compare the object to a car passed in as an argument
• A toString method that will return the VIN, make, model, and year, as a string

4) Write a Java class to encapsulate the concept of a parking garage for car objects (defined in #3). The class should include:

• Private instance variable for the parking garage address (string, e.g. 740 Park Avenue)
• Private instance variable that is an ArrayList to hold car objects
• A constructor to set the address to a value passed in as an argument, and instantiate the ArrayList to be empty
• An accessor method for the address
• An accessor method that will return, but not remove, the car object from the ArrayList at a given index that is passed in as an argument
• A mutator method for the address
• A mutator method that will add a car object at the end of the ArrayList
• A mutator method for that will remove and return a car object from the ArrayList at a given index that is passed in as an argument
