In java please help with the following: Consider given the FileProcessor a class. Because this class locks some computer resources it is required that this class is instantiated only once. Using singleton design pattern create an application (create all necessary classes and implement the application main method) that will enforce the unique instantiation of the given class.

Classes - Continued... Write a definition of a class and write a program that implements all the functionality of the class that has the following properties. The Main Program should invoke all functionality of this class, i.e., secretType. Input: from a file - the person's name and age and weight and height Output: The Original input and based on their BMI, their weight status. The name of the class is secretType. a. The class secretType has four member variables: name (a string), age and weight (int), height (double) b. The class secretType has the following member functions: (Make the accessor functions const) с. i. print – outputs the data in the member variables in a nicely formatted ii. setName - sets the name iii. setAge – sets the age iv. setWeight – sets the weight setHeight – sets the height V. vi. getName – value returning function returns the name vii. getAge – value returning function returns the age viii. getHeight – value returning function returns the height ix....

: Imagine you have a call center with three levels of employees: respondent, manager,and director. An incoming telephone call must be first allocated to a respondent who is free. If therespondent can't handle the call, he or she must escalate the call to a manager. If the manager is notfree or not able to handle it, then the call should be escalated to a director. Design the classes anddata structures for this problem. Implement a method dispatchCall () which assigns a call tothe first available employee.

need help with c++...Please explain the code and the question TOO.

Part 1. Create a Parent Class Create a complete Java class that can be used to create a Computer object as described below: A Computer has-a: Мапufacturer Disk Size Manufacturing Date Number of cores a) Add all instance variables (data encapsulation is expected) b) The class must have getters and setters for all instance variables c) The class must have two constructors, a no-arg and a constructor that receives input parameters for each instance variable. d) Implement toString() method for your class

Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string) ClassRegistration -...

Written in Python It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Docstrings for modules, functions, classes, and methods

in visual c# (windows form app) no console or Console.WriteLine Design a non-static method that can be contained within an... Design a non-static method that can be contained within an instance/object of the MyCallback delegate type. This method should display values of two data fields contained within the object that is passed to the method. Make-up your own method definition that meets these requirements.

{In Java Programming Please} Create a class hierarchy that represents different types of employees in a company. Start with a class called Employee that has two methods: calculateSalary() and displayDetails(). Then, create two subclasses of Employee: Manager and Engineer. Override the calculateSalary() method in both subclasses to calculate the salary based on their job role and experience. Override the displayDetails() method in both subclasses to print out a message indicating the details of the employee. Next, create another class called Salesperson that extends Employee and has a method called calculateCommission(). Create two subclasses of Salesperson: SeniorSalesperson and JuniorSalesperson. Override the calculateCommission() method in both subclasses to calculate the commission based on their sales performance. Override the displayDetails() method in both subclasses to print out a message indicating the details of the salesperson. In the main method, create objects of each class...

Java - OOP

In the class diagram below we have a parking charge class for an object-oriented parking system that is to be designed using java. Briefly explain any implementation decisions and the reasoning behind those without writing the complete code. N.B explain how the implementation will proceed instead of writing code

Design an interface Polynomial that defines the following operations. This is your polynomial abstract data type. Specifically this interface should have the following method signatures: A method addTerm that takes a coefficient and a power (both integer numbers) and adds the resulting term to the polynomial. (This will enable you to build a polynomial term-by-term.) It should throw an IllegalArgumentException if a negative power is passed to it. A method removeTerm that takes a power and removes any and all terms in the polynomial with that power. A method getDegree that returns the degree of this polynomial. A method getCoefficient that takes a power and returns the coefficient for the term with that power. A method evaluate that takes a double-precision decimal number and returns a double-precision result. A method add that takes another Polynomial object and returns the polynomial obtained by adding the two polynomials. Any implementation should ensure that this method does not...
