INSTRUCTIONS:
Provide answers in the rectangular areas provided.
You will be penalized if your code is not efficient.
On the reverse side you will see a driver and expected output that relies on the class you are expected to implement. You can ignore it
if you know what to implement. The driver relies on a method (getCount()) that you don’t need to implement.
Define a class called Room based on the specifications below. The class defines the following private variables:
private String id; /* Represents the room’s id */
private int beds; /* Specifies the number of beds in the room */
private double cost; /* Daily cost of the room in dollars */
private String guests; /* String with the names of guests */
private static int count; /* Keeps track of the number of Room objects created */
1. Constructor - It has three parameters (id, beds, and cost). The constructor will initialize the corresponding instance variables and
update the count static variable so we can keep track of how many Room objects have been created. Also the method will
initialize the guests instance variable to the empty string. You can assume the parameters are valid (e.g., no null references and
numeric values are greater than or equal to 0).
2. Default constructor - It initializes the object with id, beds, and cost values that correspond to “NONE”, 2, and 50.25,
respectively. You can implement this method using any approach. Remember to increase the count variable.
3. Copy constructor - Creates a duplicate of the parameter in such a way that changes to the parameter will not affect the new
object. You can implement this method using any approach. Remember to increase the count variable.
