This is the question I am stuck on - A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4).

Add a list of procedures in your patient class, fill them and print them with the patient data. 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…
Implement a Person class with the following attributes: Name: String Place of Birth: String Birthdate: Date Gender: String The constructor will receive the name and birthday date. The gender and the place of birth should be initialized as empty strings. Make the attributes private and create getter and setter methods. Write a __str__ method that prints the name and the age of the person (check the testcase for the format). To calculate the age just subtract the year of birth to the current year (don't worry about the day/month, it is not an objective of this exercise). A datetime object has a year attribute that is public. To get the current date, use: datetime.date.today() which also has a year attribute.

Create a class called StatSet that can be used to do simple statisticalcalculations. The methods for the class are:__ init __ ( self ) Creates a StatSet with no data in it.415addNumber ( self , x) x is a number. Adds the value x to the statSet.mean(self ) Returns the mean of the numbers in this statSet.median( self ) Returns the median of the numbers in this statSet.stdDev( self ) Returns the standard deviation of the numbers in this statSet.count ( self ) Returns the count of numbers in this statSet.min(self) Returns the smallest value in this statSet.max (self ) Returns the largest value in this statSet.

Default is "00-000000" o internationalService : private boolean indicating whether international calls are allowed or not. Default is false. o minutes: private int representing the number of minutes to be invoiced (added to the bill). Default is 0. o costPerMinute: private double representing the cost of 1 minute. This value should be positive. Default value is 0.2. Assume all the sim card has the same cost rate per minute. LS) The no-arg constructor that will create a new SimCard with the default…
9-10. Imported Restaurant: Using your latest Restaurant class, store it in a module. Make a separate file that imports Restaurant. Make a Restaurant instance, and call one of Restaurant’s methods to show that the import statement is working properly. 9-13. Dice: Make a class Die with one attribute called sides, which has a default value of 6. Write a method called roll_die() that prints a random number between 1 and the number of sides the die has. Make a 6-sided die and roll it 10 times. Make a 10-sided die and a 20-sided die. Roll each die 10 times. 9-14. Lottery: Using the list called series, write a function called get_winning_ticket_number that randomly select four numbers and four letters from the list. Create a list called winning_ticket_list which contains 10 winning ticket numbers. Print this list. series = ["0","1","2","3","4","5","6","7","8","9","A","B","C","D"]
IN JAVA LANGUAGE Write an ATM class with an ArrayList of Account objects as an attribute. In the constructor, add 3 Account objects to your ArrayList. They can all have a start balance of $100 and an annual interest rate of 0.12. Include two methods, menu and makeSelection as outlined below. Please note that since both methods get user input, create a Scanner attribute to use in both. menu method This method does not have any parameters and does not return a value. It should: Get the account number from the user. This corresponds to the index of the items in the ArrayList. Since there are 3 elements in your ArrayList, you are going to ask them for a number between 1 and 3, but keep in mind that the indices of the ArrayList are 0-2, so you'll have to adjust the value you get from the user accordingly. Present the user with a main menu as shown below: Get their menu selection Call the makeSelection method, passing it the account index obtained in step 1 and the menu selection…
