Suppose a call center has three levels of employees—respondent, manager, and director. An incoming telephone call must first be allocated to a respondent who is free. If the respondent cannot handle the call, the call must be escalated to a manager. If the manager is occupied, then the call should be escalated to a director. Design your own classes and data structures for this problem. Implement a method dispatchCall() that assigns a call to the first available employee.

- Suppose a call center has three levels of employees: respondent, manager, and director. An incoming telephone call must first be allocated to a respondent who is free. If the respondent cannot handle the call, the call must be escalated to a manager. If the manager is occupied, then the call should be escalated to a director. Design YOUR OWN classes and data structures for this problem. Implement a method dispatchCall() that assigns a call to the first available employee.Climber is a class that has been defined, and the variable cat refers to a Climber instance. With an argument of 4, call the method stairs on the instance referred to by cat.This is a python script.In this problem you will implement a simple library system based on object-oriented approach (using inheritance, polymorphism and abstract classes). At the library we have items and people are allowed to borrow them for a while or use them in the library premises. We have 3 types of items at the library. Books, Magazines and Compact Discs (CDs). All items have a unique number called serial number, shelf number that the item put on that shelf and shelf index, the index of the item at the shelf. Items at the library have additional different properties changing to item type. For example books have name, publisher name, and author name. CDs have title property and magazines have name, publisher properties. But people are allowed to borrow only books and CDs, but not magazines. Suppose that two kinds of people using library items. These are students and academic staff. Students can borrow only one item at a time, and academic stuffs can borrow at most 3 items at the same time. Also people…
- Programing language is Java. Define a class Person that represents a person. People have a name, an age, anda phone number. Since people always have a name and an age, your class shouldhave a constructor that has those as parameters. Define a toString() method whichdisplays all of the relevant information using a format like this: “Jim Lahey - Age 57- Phone 9025555555”.JAVA A company needs to develop an object-oriented library with a few Java classes forthe following task. Overall, they want the classes to model the geometric shapes and calculatetheir areas. These geometric shapes include Square, Rectangle, Circle, and Triangle.The above four shapes share common attributes such as name and color. The area of a shapecan be calculated by using a method area( ) which can be implemented only until the exactshape is known. Different shapes need a different area( ) method.1) Design a Java abstract class called Shape to model this situation, which will serve as a parentclass. Write its code;2). All the above shapes should be drawable by the users by calling the draw( ) method.Different shapes are drawn differently. You should design a Java interface named Drawableto provide this method for the shape classes to implement in their own ways. Write its code;3). Write the code for the four classes: Square, Rectangle, Circle, and Triangle.Note:• You should decide…IN C++ Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Provide another parameterized constructor which takes both efficiency and fuel as parameters. Also supply methods getGasInTank, returning the current amount of gasoline in the fuel tank. getEfficiency() return the efficiency of car. setGasInTank(double fuel), to add gasoline to the fuel tank. setEfficiency(double efficiency) Supply a method Drive () that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank according to its efficiency. Sample usage: Car myHybrid (50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.Drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank Supply a main method that tests…
- In C++ Language using Functions and Pointers PROBLEM: Consider the elevator in the Faculty of Engineering (5 storey). Write a program which accepts the floor number where a passenger (student/faculty/other personnel) will ride the elevator. The passenger can then input the target destination floor. SPECIFICATIONS: Implement the class diagram below: Inside the main method, create an instance of the class Elevator. Use the goUp or goDown methods to generate the program display.Passenger can ride in any floor (1,2,3,4 or 5). Program will prompt the user with the target destination floor. After the user input: Program will display the floors which the elevator passes through, and finally the destination floor. Elevator will not move if the input for destination floor is the same as the present floor. Program will notify the user and then terminate. Program will also terminate if the input destination is not 1,2,3,4 or 5. You’re free to format the input/output display. Observe proper…Consider writing a program to manage a collection of movies. There are three kinds of movies in the collection: dramas, comedies, and documentaries. The collector would like to keep track of each movie's title, the name of its director, and the year the movie was made. Some operations are to be implemented for all movies, and there will also be special operations for each of the three different kinds of movies. How would you design the class(es) to represent this system of movies? Your design should implement the concept of OverridingNote:This is a Java program question. Q#6: Create a class for invoice item having attributes invoice id (it’ll be unique for every invoice item), item description (name of product and details), quantity (number of items), and price (sail price). There is behavior to set all values. There is a display method that will show invoice id, item description, quantity, price of single item and total amount of the invoice item. Create objects to show following details. ID Name Quantity Price Total Amount 1. Chips 50 mg small pack 12 10 120 2. Chocolate Biscuit small pack 15 5 75
- Read the following scenario: To implement an exam, an instructor first notifies the students of the exam date and the topics to be covered. The instructor will prepare the exam paper, gets it copied to produce enough copies for the class, and hands it out to students at the designated time and location. The students attempt their answers to exam questions and hand in their answer papers to the instructor. The instructor then gives the answer papers to the tutor, along with sample solutions to each question, and gets them to mark it. The tutor will then records all the marks and return the answer papers to the students. After the answer papers have been returned to the students, they can raise any issues or queries about the marks they received. The instructor then reviews these queries/issues and decides whether marks adjustments are needed. If there are marks adjustments, the instructor will request the tutor to make the necessary changes in the marks record. Draw a sequence diagram…Java Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.write a java program This composition example contains classes Date, Employee and EmployeeTest .Class Date declares instance variables month, day and year to represent a date. The constructor receives three int parameters. It has checks to validate the month—if the value is out-of-range the method throws an error message, same goes for day. Provide getters, setters and toString method. Class Employee has instance variables firstName, lastName, birthDate and hireDate. firstName and lastName are references to String objects. Members birthDate and hireDate are references to Date objects. • The Employee constructor takes four parameters—first, last, dateOfBirth and dateOfHire. Initialize the hireDate and birthDate with these objects by calling its constructor and setters. • When class Employee’s toString method is called, it returns a String containing the employee’s name and the String representations of the two Date objects. Each of these Strings is obtained with an implicit call…
