- In a university there are different classrooms, offices and departments. A department has a name and it contains many offices. A person working at the university has a unique ID and can be a professor or an employee. "A professor can be a full, associate or assistant professor and he/she is enrolled in one department. •Offices and classrooms have a number ID, and a classroom has a number of seats. • Every employee works in an office. 1. Draw the class diagram for the scenario aboveMake an interaction diagram for the parking office class below. We have included the class code below. The diagram should not be hand-drawn Use the class diagram to better understand all classes in our system public class ParkingOffice {String name;String address;String phone;List<Customer> customers;List<Car> cars;List<ParkingLot> lots;List<ParkingCharge> charges; public ParkingOffice(){customers = new ArrayList<>();cars = new ArrayList<>();lots = new ArrayList<>();charges = new ArrayList<>();}public Customer register() {Customer cust = new Customer(name,address,phone);customers.add(cust);return cust;}public Car register(Customer c,String licence, CarType t) {Car car = new Car(c,licence,t);cars.add(car);return car;}public Customer getCustomer(String name) {for(Customer cust : customers)if(cust.getName().equals(name))return cust;return null;}public double addCharge(ParkingCharge p) {charges.add(p);return p.amount;}public String[]…Using UML class diagrams, create a design for the following (you can defer declaring the types for any instance variables and instance methods as long as you represent the concepts appropriately). NB: You may hand-draw your diagram or use a drawing program (your choice). Upload your finished answer for (a) and (b) as one file. (a) An Employer has one or more Employees. An Employee has exactly one Employer. Employees have attributes for their name, salary and job title (b) We are producing a vehicle registration system for the local DMV/RMV. Model the following using a UML class diagram. Read the entire specification before proceeding (this is ONE question, broken into 4 segments for readability): (i) Our interface (protocol/contract) IVehicle states that all vehicles can register() and calculateExciseTax(). These operations are public and the Vehicle contract is stable – it will not change. (ii) We think we’ll be able to take advantage of code-reuse, so your team must introduce an…
- Overview: The Observer Design Pattern is a way to design a subsystem that allows many objects to respond automatically to changes of a particular object that's being "observed". Task: Let's say that we have a bank system and this is a main branch (observed class) and there are three branch of bank (concrete class) where is notification supposed to receive by each of those branch notifySubscribers() method. Objectives: • Create a Class UML Diagrams using the Design Patterns showing the Observer Design Pattern. In java code, Create classes and all attributes and methods for the classes.Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…Class Employee Employee -Name (string) -ID(integer) -Address(string) -Salary(double) -Nationality(string) -ExtraWHours(int) +>( Name,ID) +void setdata( Address,Salary, ExtraWHours) 1. Regarding to the UML diagram create class Customer 2. Create the constructer Employee that read the Employee Name and ID and set the Nationality to Kuwaiti 3. Use the method setdata that set the remaining class data , this method verify that the number of extra working hours is greater than 5 to set the number to ExtraWHour otherwise set the number 1 + Overtime() to this data member + . get methods 4. create gets methods for all data member 5. calculate Employee overtime in Overtime method this method return double value after calculating the overtime by using the following formula Overtime = (Salary * 0.25)* ExtraWHours Test File 1. declare the object Employee1 with Name Fahad and id 7788 2.

A navigation system is to be developed to help the delivery riders to deliver food to their customers. You are asked to design the UML Class Diagram for the system based on the following: A navigation device belongs to only one rider's vehicle. A navigation device can calculate at least zero route. In return, every route can be calculated by many navigation devices. A route has at least one road segment, and every road segment belongs to many routes. A road segment is defined by road name as well as start and end points. "Navigation device with congestion avoiding" is a specialization of the navigation device, and it queries many traffic jam information. Your diagram must include any related relationships i.e. generalization, aggregation and/or composition and multiplicity.
- Create a UML class diagram using arrows to show the relationships between classes for the following scenario. The class diagram is attached for reference. A parking deck system manages an entry/exit gate, which opens to let a vehicle (i.e., car) into or out of the deck and closes when the car has passed through. A driver must push a button to print a parking permit. When the driver takes the parking permit, the system raises the gate. The system lowers the gate after the vehicle has passed through. A permit id and time of entry is printed on the parking permit, and is also encoded on the permit’s bar code. When the vehicle leaves the parking deck, the driver inserts the parking permit into a bar code reader, which scans the bar code, and then transmits the bar code to the parking system. The parking system calculates a fee that is based on the number of hours that have elapsed since the vehicle entered the parking deck, and displays the fee to the operator and driver. The driver must…9. Draw Class diagram for, customer order from a retail catalog. The central class is the Order. Associated with it are the Customer making the purchase and the Payment. A Payment is one of three kinds: Cash, Check, or Credit. The order contains OrderDetails (line items), each with its associated Item.4. Consider a Person class (which keeps track of a Person’s name) and a Student class (which keeps track of a Student’s name and student ID number). State the relationship between the two classes as either an is-a or a has-a relationship (similar to the last sentence of each paragraph in the above Model).
