D Create a class Sum with the following fields, constructors and methods: Fields: create two integer fields Constructors: - a no-argument constructor - a constructor with two parameters Methods: - write a getter to return the sum of fields - Create 4 overloaded calculate methods 1. method receives two integer parameters and returns the sum 2. method receives four integer parameters and returns the sum 3. method receives two double parameters and returns the sum 4. method receives two String parameters and returns the sum Create a demo class to test the two constructors, all the methods and display the returned values. You can hard code the parameters values. Make sure the four methods created are toverloaded i.e. same method name for all four.

Write the definition of a class Player that has the following methods: • An __init__ method that initializes the following attribute variables: o An attribute variable named name , initialized to the empty string. o An attribute variable named score , initialized to the value 0. • A method named set_name that accepts one argument that is assigned to the attribute variable name . • A method named set_score that accepts one argument that is assigned to the attribute variable score . • A method named get_name that accepts no arguments, and returns the value of the attribute variable name . • A method named get_score that accepts no arguments, and returns the value of the attribute variable score .
Modify the Car class example and add the following: A default constructor that initializes strings to “N/A” and numbers to zero. An overloaded constructor that takes in initial values to set your fields (6 parameters). accel() method: a void method that takes a double variable as a parameter and increases the speed of the car by that amount. brake() method: a void method that sets the speed to zero. To test your class, you will need to instantiate at least two different Car objects in the main method in the CarDemo class. Each of your objects should use a different constructor. For the object that uses the default constructor, you will need to invoke the mutator methods to assign values to your fields. Invoke the displayFeatures() method for both objects and display the variables. Demonstrate the use of the accessor method getColor() by accessing the color of each car and printing it to the console. Use the method accel to increase the speed of the first car by 65 mph. Use…
1 - 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…
in Java, 1. Write a class called Counter that has the following:- Data field counterIndex- Default constructor: initializes data field to zero- Overloaded constructor: parameter passed to initialize the data field- Write a getCounterIndex method: returns the counterIndex - Write a setCounterIndex method: sets the counterIndex to some value that is passed to the method- increase method: increase the data field by 1- decrease method: decrease the data field by 1 2. Write a CounterTest programWrite a main method that contains the following:- Create a Counter object called counter1 using the default constructor- - Create a Counter object called counter2 using the overloaded constructor and pass the value 5- Get the counter index for each object and store the values in integer variables a and b- Test if a is greater than b increase counter1, otherwise decrease counter1- Print the counter1 value after the test
Make a class with name(TerminalExam). Declare two variables i and j of type int in it. In constructor, initialize these variable with values specified in parameters. Make a method named calculate in this class of double return type. In this method, perform the addition of i and j and display the result. Make a second class(SubC2) which inherits from first class (TerminalExam). In this class’s constructor, pass two values as parameters but initialize the fields using superclass’s constructor. Override the method calculate() defined in superclass. In overridden method, calculate the difference of i and j and print the result. Then create a class in the same way for multiplication and division and override the method for multiplication and division respectively. Make another class(Add3V) which extends TerminalExam. In this class, declare a variable c of int type. In constructor of Add3V, call superclass constructor and then set value of c also. In calculate method, first call calculate…

this is for a python class 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt Ex. If a new Product object is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is: Name: Apple Price: 0.40 Count: 3 Ex. If 10…
