Identify different states of control software object for an automatic washing machine that has different programs for different types of clothes. Also list a few events/triggers that cause state changes. Provide at least 4 states and 4 transitions. Answer to this question can be just a list of states and transitions. You do not need to provide a UML state diagram. Sample Response to this question (use this an example to construct your response): States: s1 s2 Transitions: event xx causes transition from state s1 to state s2 event yy causes transition from state s2 to state s3

Q No. 2: Draw a Use Case diagram for "The Pizza Ordering System". (Hint – correct > or > relationships will attract additional marks). The Pizza Ordering System The Pizza Ordering System allows the user of a web browser to order pizza for home delivery. To place an order, a shopper searches to find items to purchase, adds items one at a time to a shopping cart, and possibly searches again for more items. When all items have been chosen, the shopper provides a delivery address. If not paying with cash, the shopper also provides credit card information. The system has an option for shoppers to register with the pizza shop. They can then save their name and address information, so that they do not have to enter this information every time that they place an order.

Make the uase cases into UML class diagram and add the type of attributes and functions. Make sure to also write a python code to print an object (Customers Bill).

Write the code for the following UML diagram.Vehicle -color:String-speed:double-fuel:double+state: String+input():void+addFuel(): double+moving():void+stop():void+display():void   1. Input(): Ask user to provide values for color and fuel. Default values for speed is “0”and state is “stopped”2. addFuel(): Ask user to provide value for fuel to add. Add that value in fuel (attribute)and return value of total fuel.3. moving(): Ask user to provide the speed of vehicle and fuel consumption. Set the valueof speed and reduce the fuel (attribute) according to fuel consumption. And also set thestate to “Moving”.4. stop(): This method will display that “Vehicle is stopped” and sets the value of speedto “0” and state to “Stopped”5. display(): This method will display the attributes value to output like:“Vehicle is stopped. It has red color. It’s speed is 0.0 and fuel is 2.5 Liter”

I can make the application but seem to always have issues with the Class UML Diagram.  Below is the program I made and I attached the UML diagram.  I was not completely sure about the Guest guest1 = new Guest (" ", " ") objects in the UML diagram.  Any Advice? //-------------------First class: public class Guest { // Attributes belowprivate String firstName;private String lastName;//constructor belowpublic Guest(String firstName, String lastName) {this.firstName = firstName;this.lastName = lastName;} // Overloaded constructor belowpublic Guest() {this("No First Name Given", "No Last Name Given");} public String getFirstName() {return firstName;} public void setFirstName(String firstName) {this.firstName = firstName;} public String getLastName() {return lastName;} public void setLastName(String lastName) {this.lastName = lastName;} @Overridepublic String toString() {return firstName + " " + lastName;}} //------Second class import java.util.ArrayList; public class GuestList {public…

The object-oriented design techniques that are used should be arranged in such a way that modelling comes before procedure whenever possible. Put out your most compelling argument.

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…

Programming to be used: Java Instructions: Develop a UML class diagram for the following situations. Your diagram should be able to specify correctly the following: Class Name, Attributes with their corresponding data type and visibility, Methods with their corresponding data type. Use the text editor or MS word to present your answers. Scenarios: 1. The university wants you to design an enrollment system. One of the classes to be considered is class STUDENT. A student during registration can have his ID number. Information about the student (eg. First name, middle name, middle initial, contact number, address, birthday) are asked and stored in the system. These information, however, can be edited. After the registration/admission, a student can enroll subjects, can add subjects and can drop subjects. 2. The same University asks you to design a Human Resource Information System. This is a system that records information and generates reports about the employees in the university. Each…

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…
