Create an object-oriented program that tracks your progress as a student in this class using 2 sources
down below.The program should keep track of your name and your scores on graded activities in this
class. The scores on each test, each homework, and each final should be stored separately. The program
should allow a student to enter his or her name, a test score, a final exam score, and a homework
assignment score. Scores for tests and finals can range from 0 to 20 and homework scores can
ange from 0 to 2. Any time a user enters an invalid value that value will be ignored and will not
e saved.
Since this program is object-oriented it must be developed first as a class called Student. This
class should store name and the student scores as instance variables. There should be one
instance variable for each of the following: name, concept test 1, programming test 1, concept
test 2, programming test 2, homework 1, homework 2, homework 3, homework 4, homework 5,
homework 6, homework 7, homework 8, homework 9, homework 10, concept final, and
programming final. These instance variables should be made private to prevent invalid values
from being stored in them, but there should be ways to access and mutate these instance
variables using public methods. This class should also have a default constructor (no
parameters) setting the name to blank and making each of the other scores of the student set to 0.
The second part of this program should be developed in a class called StudentDemo. This class
will have a main method inside of it where an object of the Student class will be created. Then
the user will be given options to update their name or any of their scores. There should be an
option for each test, final, and homework. Finally there should an option to look at all the
information about the student. This main method should also have a loop to allow this program
to continue running until the user chooses the last option which is to exit the program. If the use
chooses an invalid option then an e
or message should be printed and the program should
continue running until the user chooses to exit the program.

Programming Test 1
Instructions
Students are allowed to use their ZyBook and the notes posted on Canvas as well as an IDE
(Integrated Development Environment) to complete this test. Students are not allowed to use any other
esources except those mentioned above. Students should also not communicate with any other person
about this test either before, during, or after taking the test. This test does not have a time limit, but it
does need to be turned by the deadline posted on Canvas. Tests that are not turned in by the deadline
are subject to the late penalty described in the syllabus.
Please make sure to only implement what is asked for. You may not add any instance variables
to any class, though you may create local variables inside of a method to accomplish its task. No other
methods should be created other than the ones listed here. You will lose points if you do not follow
these directions. The grading criteria is listed at end of the document.
Requirements Analysis
Create an object-oriented program that allows a user to keep track of the book they are cu
ently
eading. The program should allow the user to change the name of the book, change the number of
pages in the book, and the cu
ent page they are cu
ently on in the book. The number of pages in a
ook must be greater than 0 and also greater than or equal to the cu
ent page the reader is cu
ently on.
The cu
ent page must be greater than 0 and also less than or equal to number of pages in the book.
Any time a user enters an invalid value that value will be ignored and will not be saved.
Since this program is object-oriented it must be developed as a class called Book. This class
should store name of the book, the number of pages, and cu
ent page as instance variables. There
should be an instance variable for each these. These instance variables should be made private to
prevent invalid values from being stored in them, but there should be ways to access and mutate these
instance variables using public non-static methods. There should be a separate method to access each
instance variable. There should be a separate method to mutate each instance variable. This class
should also have a default constructor which sets name instance variable to No Name Yet and sets
number of pages instance variable to 0 and sets cu
ent page instance variable to 0.
The second part of this program should be developed in a class called BookDemo. This class
will have a main method inside of it where an object of the Book class will be created. Then the user
will be given options to update the name, number of pages, and the cu
ent page. There should be an
option for each of these. Finally, there should be an option to look at all the information about the
ook. This main method should also have a loop to allow this program to continue running until the
user chooses the last option which is to exit the program. If the user chooses an invalid option then an
e
or message should be printed to the screen. The program should continue executing until the user
chooses to exit the program.
