Task 2: Delivery Vehicle We want to develop a delivery vehicle that can carry a limited number of equally weighted boxes. To do this we can build off of our previous task by extending the BasicVehicle class. Instructions 1. Create a new class called DeliveryVehicle that is a subclass of BasicVehicle: • a private attribute cargoList of type String[] • a private attribute numItems of type int 2. Create a constructor that takes two parameters: a String for registration, and an int for maxCapacity: • pass on the registration parameter to the super constructor along with 0.0 for altitude, longitude and latitude. • use the maxCapacity parameter to create a new array for cargoList 3. Create a boolean method called isFull that returns if the cargoList is full. 4. Create a boolean method called isEmpty that returns if there are no boxes loaded. 5. Create a method called loadCargo that takes a String parameter description and adds the cargo description to the cargo list (if it is not already…
Class: Square Create a class called "Square", which is inherited from“TwoDimensionShape” class. The "Square" class is used to calculate theArea and the Perimeter of square shapes when their side-length is given, or in contrast,finding the side-length of the square when the Area or the Perimeter of the square is given.The specifications of this class are below. Data Members (Attributes): All are private. sideLength: the sidelight (L) of the square. Methods/Operations/Getters/Setters: Default Constructor: when creating an object this constructor must set the side-length of the square by calling the method setSideLength(). Also, this constructor willcall the findArea() and the findPerimeter() in addition to summaryPrint() to calculateand print all needed information. User-Defined Constructor: when creating an object this constructor shouldfind the side-length of the square by calling the method findSquareSideLength()and pass the Area or the…
Information: Java Script There are two types of accounts - S for short term contract and L for long term contract. 3.1 Create an Employee objects project. Create an Employee class and use the provided UML diagram to code the instance fields, constructors and methods. 3.1.1 Both constructors must increment the static numberOfEmp field by one. Both constructors must call the setEmpCode() method to compile a code for the employee. Both constructors must call the setCommission() method. 3.1.2 setEmpCode() method: The empCode must be constructed in the following way: First character is the type of contract Next three characters a random 3 digits Add a backslash and the number of objects value to the code NOTE: You have to use the Random class in your code (See Ch 9). Do NOT use the Math.random() method. Example of code: S781/1 Explanation: Short term contracts (S), 781 is the 3-digit random value, first employee object. 3.1.3 setCommission() method: Assign a basic amount to the…

Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.
2-) Write a superclass encapsulating a rectangle. A rectangle has two attributes representing the width and the height of the rectangle as a data members. It has methods returning the perimeter(P=2*(L+W)) and the area of the rectangle(A=L*W). This class has a subclass encapsulating a parallelepiped, or box. A parallelepiped has a rectangle as its base, and another attribute named depth. The derived class Box should have a constructor, a volume() function and an override function named area () that returns the surface area of the box. Include the classes constructed in a working C++ program. Have your program call all the member functions in each class and verify the results manually.

1. Part 1: A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design the class Point that can store and process a point in the x-y plane. Your class should contains the following methods. Default constructor without parameters that initializes the private data member to the suitable values Constructor with parameters sets the values of the instance variables to the values of the parameter. Accessor methods that return the values of the x-axis and y-axis. setPoint method which set the values of x-axis and y-axis makeCopy method that make a copy of a received object of type Point. getCopy method that returns a copy of the current object toString method that returns the object string isEqual that returns true if the current object is equal to the received object of type point distance, which receives two objects of type Point and returns the distance
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…
