- Consider a call centre with three personnel levels: responder, manager, and director. An incoming phone call must first be assigned to a responder who is available. If the respondent is unable to handle the call, it must be escalated to a management. If the manager is unavailable or unable to address the situation, the call should be escalated to a director. Create the classes and data structures needed for this problem. Create a dispatchCall () method that allocates a call to the first available employee.Consider a call centre with three personnel levels: responder, manager, and director.

Create a dispatchCall () method that assigns a call to the first available employee.Design and implement a Restaurant class with at least three meaningful attributes and two methods. Implement a test program which creates at least two instances of the restaurant class and calls all the methods. Some possible attributes are name, numberOfTables, cuisine, numberOfReservations, capacity, etc. Some possible methods are make Reservation, checkAvailability, etc. Note the following: Deliverables include a Java program (.java) - All properties must be declared as private and you need accessor and mutator methods for each property. - You need to define at least one constructor. Documentation o Include header comments that include description of the program. o Include body comments o Consistent indentations o Consistent white line spaces o Properties are declared private o Accessor and mutator methods are created o At least one default constructor o At least two instances are created
- 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.Complete the thick.h, thick.cpp, thin.h, and thin.cpp classes in the attached pizza solution. Modify your main.cpp class so that it creates a thin and thick crust pizza if selected by the user. Your solution should allow the user to order a regular, stuffed, thin or thick crust pizza. All child classes (stuffed, thin, thick) should inherit attributes and functions from the Pizza class. The stuffed class has already been implemented. The thick and thin class set_cost() funtions should differ in the following ways: thick crust has an additional charge of $2 thin crust has a cost discount of $1A list of projects and a list of dependencies, or a list of project pairings where the second project depends on the first project, are provided to you. Before starting a project, all of its dependencies must be built. Find a build order that enables the construction of the projects. Return an error if there is no proper construction order. EXAMPLEInput:projects: a, b, c, d, e, fdependencies: (a, d), (f, b), (b, d), (f, a), (d, c)Output: f, e, a, b, d, c
- When one class includes objects that belong to another class, this is known as a whole-part relationship or composition. The conclusion is that a has-a connection exists. Consider the following lengthy assertion: getHireDate(), getYear(), and Outputsales.getHighestPaidEmployee() are some useful functions ().Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit only one class: MyDate.java. Do NOT include "public static void main()" method inside all of these classes. The classes would be tested, using the unit-testing framework JUnit 4. A class called MyDate, which models a date instance, is defined as shown in the class diagram. The MyDate class contains the following private instance variables: year (int): Between 1 to 9999. month (int): Between 1 (Jan) to 12 (Dec). day (int): Between 1 to 28|29|30|31, where the last day depends on the month and whether it is a leap year for Feb (28|29). It also contains the following public static final variables (drawn with underlined in the class diagram): MONTHS (String[]), DAYS (String[]), and DAY_IN_MONTHS (int[]): static variables, initialized as shown, which are used in the methods. The MyDate class has the following public static methods (drawn with underlined in…Scenario: You are tasked with the development of an E-Scooter ride-sharesystem. It allows registered commuters to approach an idle E-Scooter andreserve it, following which they use the E-Scooter to commute a certaindistance (that is not known prior to use). Finally, after the commuter reachestheir destination, they end the ride, which prompts an automaticcomputation of the ride fees. which is automatically debited using thecommuters registered payment details.Task(s):A. Create an AOM Goal diagram based on your identified Roles and Goals.Please make sure your diagram has at least 3 levels of hierarchy.

Task(s):1. Create a CPN model based on the AOM Goal and Behavioural InterfaceModels using the mapping heuristics discussed in the lecture.2. The initial tokens (initial state) of your system should reflect at least 2scooters and 2 commuters. More generally → Please ensure a level ofcomplexity similar to the CPN model example given in the lecture.3. You can use the CPN model example used in the lecture and modify itto suit your needs.4. You are welcome to use hierarchical CPNs to follow the Goal hierchy ifyou like, but it is not…To put it another way, when one class includes objects of another class, we have a whole-part link, also known as composition. The connection formed is a "has-a" one. Please consider the following lengthy statement: For example, we may use the outputsales.getHighestPaidEmployee(), outputsales.getHireDate(), and outputsales.getYear() functions to get the highest paid employee ().Implement the class as depicted in the UML diagram. Apartment -city: String -area: double -nbOfRooms: int -duplex: boolean +num apt: int +Apartment(----All data fields----) +getCity(): String +getNumberOfStories(): int +assessSize(): String +printDescription(): void 2/3 Data Fields: 1. city: It may consist of one word or two such as "Beirut", "Bint Jbeil", etc. 2. area: its value is expressed in square meter 3. nbOfRooms: with maximum value of 10 4. duplex: either true or false to reflect whether the apartment is made of two stories or only a single one. 5. num_apt: to keep track of how many apartment objects were created. Methods: 1. A constructor that creates an Apartment object with the specified values of all data fields. If the number of rooms passed is greater than 10, then nbOfRooms is set to 0. 2. getCity(): this method returns the city with its letters all capitalized. 3. getNumberOfStories(): This method returns the number of stories of an apartment. If it is duplex, then 2…
