- in java Create a class for Student and implement all the below listed concepts in your class. Read lecture slides for reference. Class Name: Student 1. Data fields studentID name email majorDepartmentSelect proper datatypes for these variables. 2. Constructors – create at least 2 constructors No parameter With parametersSet id and name using the constructor with parameters. 3. Methods toString method : To print the details of the Student. Setter and getter methods 4. A static variable count : To keep the count of Student objects5. Visibility Modifiers: private for data fields and public for methods 6. Write some test cases in main method1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…Create a class called Student that models a student at Carleton University. A student's state consists of a name (String), id number (int) and a list of grades (array of doubles). Your class must have a constructor that has three input parameters (name, id and grade list) and sets the initial state for the object. Include a toString() method that returns a useful string representation of a student object. The string representation should contain the student's name, ID number, and the number of grades they have recorded (so NOT include all the grades). Include a gradesInRange(double lower, double upper) method that returns the number of grades that this student has that are in the range [lower,upper]. That is, the it returns the number of grades that are greater than or equal to lower and less than or equal to upper. Example Usage: Student s = new Student("cat", 100123987, new double[]{81.2, 93.2, 76,2, 84.6});int num_A_grades = s.gradesInRange(80,100);// assert num_A_grades will be 3

Trying to write this class has really been stumping me.Creates a class called CourseClass with 6 attributes: a. name: the course name; b. maxStud: a maximum number of Student into the CourseClass; c. nbStud: the current number of Student into the CourseClass. When a CourseClass is created, the number nbStud is equal to 0; d. Student Stud[]: an array of Student. The size of this array is equal to maxStud; e. CourseTeacher: the Teacher (of type Teacher) responsible of this course; f. LabTA: The TA (of type TA) responsible of the course's Lab; Add the following methods: e. Constructor: able to create a CourseClass with maximum 10 Students; f. overload the operator += (Student): able to add a Student to the CourseClass. The Student will be added to the Stud array. You need to be sure that an available space exits (uses the function assert); g. find(StudentName): this method allows to find a Student by his Name. If it exists, the Student will be displayed, else, am error message will be displayed; h. display: this method aims to display all…
- a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).Write a class Student with the following attributes (make sure the attributes are private using name mangling): name: String id : Integer courses: List of Strings grades: List of Integers The class must include the following operations: A constructor that receives as input the name and id. Getters for each attribute. add_course(course: String, grade: Integer) : Bool -- This operation adds the course name to the list of courses and the grade to the list of grades. The method must confirm before adding that the course is a String and the grade is an Integer, otherwise the operation won't be performed. The method must return True if the course and grades were added, False otherwise. __str__() -- Should return the following information "Student name: <name> -- Courses passed: <number of courses passed>". Courses passed means courses with a grade equal to 60 or larger. Check the testcase for details. pass_ratio(): Float -- Returns the pass ratio as a percentage of…Write in python and please include docstring. Write a class named Employee that has private data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address. Write a separate function (not part of the Employee class) named make_employee_dict that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary. For example, it…
