Create a class named Person.a. This class must have two variables to store name (string) and age (int). These variables should not be accessible from outside the class.b. Encapsulate the variables defined in item a with a property (an intermediate variable) so that they can be accessed from other classes. And after this step, use only intermediate variables that you defined for encapsulation within methods and other classes.c. Define a constructor method for this class. Code the constructor method to initialize the properties of the class at the time of object definition.D. Define a method called Print Info that will print the information of the class object on the screen in a proper format.
1. for this question do not write the code just explain how you would Create a class called Elevator that can be moved between floors in an N-storey building. Elevator uses a constructor to initialize the number of floors (N) in the building when the object is instantiated. Elevator also has a default constructor that creates a five- (5) storey building. The Elevator class has a termination condition that requires the elevator to be moved to the main (i.e., first) floor when the object is cleaned up. Write a finalize() method that satisfies this termination condition and verifies the condition by printing a message to the output, Elevator ending: elevator returned to the first floor. In main(), test at least five (5) possible scenarios that can occur when Elevator is used in a building with many floors (e.g., create, move from one floor to another, etc.). Hint: Termination occurs when the instance is set to null. You may wish to investigate “garbage collection” for this exercise.
Construct a Time class containing integer data members seconds, minutes, and hours. Have the class contain two constructors: The first should be a default constructor having the prototype Time(int, int, int), which uses default values of 0 for each data member. The second constructor should accept a long integer representing a total number of seconds and disassemble the long integer into hours, minutes, and seconds. The final member method should display the class data members.

Define the Artist class in Artist.py with a constructor to initialize an artist's information. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. Define the Artwork class in Artwork.py with a constructor to initialize an artwork's information. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Add an import statement to import the Artist class. Add import statements to main.py to import the Artist and Artwork classes.

Exercise 2 Design a class named Customer with field holding for customer's name, address, and telephone number. Customer's name and address can only be accessed by Customer class. Telephone number can only be accessed by its subclass. Write two overloading constructors and the appropriate setter and getter methods for the class's fields. A retail store has a preferred customer plan where customers can earn discounts on all their purchases. The amount of a customer's discount is determined by the amount of the customer's cumulative purchases in the store as follows: • When a preferred customer spends RM500, he or she gets 5 percent discount on all future purchases • When a preferred customer spends RM1,000, he or she gets 6 percent discount on all future purchases • When a preferred customer spends RM1,500, he or she gets 7 percent discount on all future purchases When a preferred customer spends RM2,000 or more, he or she gets 10 percent discount on all future purchases Design a class…
Modify the Car class example and add the following: A default constructor that initializes strings to “N/A” and numbers to zero. An overloaded constructor that takes in initial values to set your fields (6 parameters). accel() method: a void method that takes a double variable as a parameter and increases the speed of the car by that amount. brake() method: a void method that sets the speed to zero. To test your class, you will need to instantiate at least two different Car objects in the main method in the CarDemo class. Each of your objects should use a different constructor. For the object that uses the default constructor, you will need to invoke the mutator methods to assign values to your fields. Invoke the displayFeatures() method for both objects and display the variables. Demonstrate the use of the accessor method getColor() by accessing the color of each car and printing it to the console. Use the method accel to increase the speed of the first car by 65 mph. Use…
