(JAVA) The use case description for the View Exam Grades use case is described below. Determineclasses that are needed to implement the use case. Also, define each class's attributes andmethods. Represent class and its attributes and methods using the UML class notation.Use case name: View Exam Grades.Summary: The student looks at his/her exam grade of CS2365 OOP or CS3365 SoftwareEngineering.Actor: StudentPrecondition: None.Main sequence:1. The student enters the student ID and password into the system.2. The system checks if the student ID and password are valid.3. The system displays the course numbers (e.g., CS2365 and CS3365) if the ID andpassword are valid.4. The customer chooses only a course to view the grade.5. The system displays the course grade to the student.Alternative sequence:Step 3: If the student's ID and password are invalid, the system displays an error messageand asks to enter another ID and password into the system. If the ID and password arevalid, the system…

Q1:
Start with the safearay class from the ARROVER3 program in Chapter 8 of Object Orient programming by Rober Lafore. Make this class into a template, so the safe array can store any kind of data.
Include following member functions in Safe array class.
The minimum function finds the minimum value in array.
The maximum function find the maximum value in array.
The average function find average of all the elements of an array.
The total function finds the running total of all elements of an array.
In main(), create safe arrays of at least two different types int and double and store some data in them. Then display minimum, maximum, average and total of array elements.
Note: use subscript ([]) operator in sasfearay class.

- Edit only the class definition. DO NOT CHANGE the code given under 'main' please. Steps: Additionally implement any Python Magic/Dunder methods such that instances of the class minimally:1. Support addition, subtraction, equality operations and the built-in abs function2. Are Iterable i.e., support for loops and star arguments for unpacking into function calls3. Support a string representation that displays the class name and coordinates stored by the instance: i.e. for an object initialized as: Vector(0, 3), the string representation should be ‘Vector(0, 3)’The code given under main tests for each of the program requirements and subsequently uses the turtle module to plot randomly generated points rotated.

- Define the terms "type conversion," "type coercion," and "nonconverting type casts."arrow_forwardThe differences between value types and reference types applies to parameters. True Falsearrow_forwardQuestion 3 use c++ to Write a template class Point with two class parameters representing the two coordinates of the Point. Include public methods to display and set the data values as well as a function that swaps the values so that, after the swap, the first element is cast into the second and the second is cast into the first. Also write a main function that creates a Point object and calls the public methods.arrow_forward
- Explain the differences among type conversion, type coercion,and nonconverting type casts.arrow_forwardRevise the following Course class implementation in the following c++ code When adding a new student to the course, if the array capacity is exceeded, increase the array size by creating a new larger array and copying the contents of the current array to it. Implement the dropStudent function. Add a new function named clear() that removes all students from the course. Implement the destructor and copy constructor to perform a deep copy in the class. Write a test program that creates a course, adds three students, removes one, and displays the students in the course.arrow_forward(Car Class) Create a class called Car that includes three instance variables-a model (type String), a year (type String), and a price (double). Provide a constructor that initializes the three instance variables. Provide a set and a get method for each instance variable. If the price is not positive, do not set its value. Write a test application named CarApplication that demonstrates class Car's ca- pabilities. Create two Car objects and display each object's price. Then apply a 5% discount on the price of the first car and a 7% discount on the price of the second. Display each Car's price again. 3.13arrow_forward
- Write a C++ program that: • Implements a class with three data members {sum (int), count (int), avg (float)}.( Implement the following 3 member functions: • The first function is a default constructor which initializes sum and count to zero. (. • The second function is named add which receives an integer number as input parameter and add it to sum and increment count by 1. • The third function is named outmut which drvides the sum over count and save it to avg then print the avg value). • Then, write a program to read numbers from the user until entering zero. The program uses the previous class to calculate and print average of {positive, negative} numbers. (arrow_forwardDefine blanks parameter.arrow_forwardExplain well. Have a nice day:)arrow_forward
