Complete MyProgram such that you can test all conditions
In the Theater constructor you need to instantiate each seat object based upon the information passed to the constructor, making sure they are available.
In the reassign method, make sure the from and to seat assignments are within range and return false if not.
There is test cases included with this exercise, so when you submit your screenshot, it needs to show the test cases passed.
In this assignment, you will need to add a new method to the Date class, which you
can find on D2L in the "Sample Code" section.
The new method should make a Date object's day, month, and year value change to
the next day. In other words, add one day to the object's current date. Do not use any
part of the built-in DateTime class, but you may want to use the DaysInMonth()
method from the Date class.
Examples:
• If the Date object stores the date 12/31/2021, then after calling your method
it should store the date 1/1/2022
• If the Date object stores the date 2/28/2022, then after calling your method it
should store the date 3/1/2022
As noted in the common instructions, you only need to turn in your new method, not
the entire Date class.
PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. PLEASE EDIT BOTH THE TEST CLASS, DO NOT EDIT THE MAIN METHOD.
Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result.

- Write a main method, in which you should have an Arralylist of students, in which you should include every student. You should have a PhD student named Joe Smith. In addition, you should create an Undergraduate student object for each of your team members (setting their names). If you’re only one person doing the assignment, then you should just create one undergraduate object. For each undergraduate student, you should add add two courses (COIS 2240 and COIS 1020). Loop over the arraylist of students, print their names, if the student is an undergraduate student, print their courses.arrow_forwardThe first version of Abby’s Eggs worked but was a bit cumbersome. I.e. you couldn’t edit a single parameter, you had to always re-enter all of them. Store the parameters (number of chickens, eggs laid per day, etc.,) in static fields of the class. Have separate methods for updating the parameters. Use a switch statement to take menu selections for updating parameters or outputting results. If the menu choice is 0, the program should terminate, invalid inputs should be ignored and any prompt repeated. Before displaying updated menu, “clear the screen” I got most of the code working, but I can't find a way to clear the sceen before displaying the updated menu. I tried using "System.out.print("\033[H\033[2J"); System.out.flush();", but it is not working. I am using the Apache NetBeans IDE.arrow_forwardFor this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }arrow_forward
- Must be written in Python. Please include docstring and show how output should look like. Remember that all data members should be private. An object can access it's own private data members directly. It can also access the private data members of other objects of the same class directly. But when accessing a private data member of an object of another class, it needs to call the appropriate get method. If that sounds complicated, just remember this: if a method is in the same class as a private data member, then it can access that data member directly, otherwise, it needs to use a get method. Write a class named Point that has two data members, x_coord and y_coord, representing the two coordinates of the point. It should have: an init method that takes two arguments, an x-coordinate and y-coordinate (in that order), and uses them to initialize the two data members. get methods for the two data members: get_x_coord and get_y_coord. a method named distance_to that takes a Point object…arrow_forwardCreate another ticket machine for tickets of a different price; remember that you have to supply this value when you create the machine object. Buy a ticket from that machine. Does the printed ticket look any different from those printed by the first machine?arrow_forwardCopy your previous class definition for RectangularSolid from the previous problem, including both methods. Provide mutators (setters) and accessors (getters) for each of the three parameters. Use the naming convention for these methods that is demonstrated in your textbook (i.e. do not use the property function or decorators). These methods should allow a program using your code to modify the parameter values after creation and to read individual parameter values.arrow_forward

Implementing enhanced for loop (for each loop) to iterate over the numbers array in the calculateProduct method. Creating a separate class for the UI and a separate class for the calculator logic. Lastly, creating a constant instead of hard coding the number "5" in multiple places. Thank you for any input/knowldge you can transfer to me, I appreciate it.

This is called composition which is a "has a" relationship. A patient has procedures. Write a class named Patient that has attributes for the following data: First name, middle name, and last name Address, city, state, and ZIP code Phone number Name and phone number of emergency contact The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: Name of the procedure Date of the procedure Name of the practitioner who performed the procedure Charges for the procedure The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator…arrow_forwardCreate a code the follow way: Each student object should also contain thenumber of earned credits. Provide a constructor that sets this value based on parameter value. Overload theconstructor such that the number of earned credits is initially zero. Provide setter and getter for this newfield. Modify the toString method such that the new information is included in the description of thestudent. Modify the driver class main method to exercise the new Student methods.arrow_forward
- You are going to be working with class Rational which defines rational number objects. A rational number is a number that can be written as a fraction. A rational number consists of a numerator and a denominator (which cannot be 0). Rational numbers also have the ability to be displayed in an original form, decimal form or reduced form. You are going to be completing various object methods to perform the tasks previously list. You are to begin with the Rational Class and RationalTest classes provided. Make all modifications outlined in the point values below. Pay close attention to the names of the attributes, methods and return values. You are given starter files and the test files necessary. Only modify class Rational and keep the function headers provided to you for all of Part 1. You will need to add your own methods for Part 2. Part 1a This version requires that you complete the constructor, getOriginal(), and getDecimal() methods of class Rational.

Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. exisiting code in different file: const double GALLONS_IN_A_CUBIC_FEET = 7.48; class swimmingPool { public: void set(double l = 0, double w = 0, double…arrow_forwardSELECT ALL the members of the class that are accessible via a static method in the supplied class below.
