Sequence diagram:
Sequence diagram is a tool that represents the way of interaction of objects to accomplish a work. The objects are labeled with the task to be performed. The arrows show the direction of communication. Objects are shown by rectangles.

- Please answer the second part of this question (construct an FA).arrow_forwardSubject: Computer Science Question: CODE in PYTHON. Create a program that satisfy the given UML Diagram. Using this UM class diagram, create a program that will satisfy this figure. All the methods inside the class must be set to print the action being made by that method. *Example enroll() method must print out print ("Enroll"). Lastly, Instantiate an object for (Student, Admin, Lecturer).arrow_forwardExplain by giving an example of variable types.arrow_forward
- Although the book focused on the normalization process only up to the Third Normal Form (3NF), there are actually four more commonly recognized normal forms – Boyce-Codd Normal Form (BCNF), Fourth Normal Form (4NF), Fifth Normal Form (5NF), and Sixth Normal Form (6NF). Research the uses of these other normal forms, then pick one to give a brief explanation of to the class. please pick one .arrow_forwardPlease give som examples in Python for questions below. Please give detail examples Relational diagram for code (a diagram showing how classes and methods interact) Class constructors, specifically a student constructor Classes and methodsarrow_forwardYou are given the following sequence diagram. Which operations does class A have according to the diagram? a1:A a2:A a3:A b1:B c1:C X Ⓒy():void x():void z(String):void y():void x():void z(): String y():void x():void z(): String ју Z Z Z:123arrow_forward
- 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.arrow_forwardIn c#, Method is a separate code block and that contains a series of statements to perform particular operations and methods must be declared either in class or struct by specifying the required parameters. we have different ways to pass parameters to the method, Explain the different with regards to input/output with examples Initial posting and substantive replies are requierd .arrow_forwardFor this discussion, you will discuss the benefits of using methods vs sequential programs. Provide several advantages of using methods over sequential programs. For these discussions, there is not one specific answer, however in order to receive full credit you must not only provide what is requested, but also justify your statements. There is not a specific length, but you must respond in depth and thoroughly.arrow_forward
- 2. Consider the BlackJackCard and PlayingCard classes. a)Do these two classes have an is-a or has-a relationship? b)Which class is the more general class? c)Which class is the more specialized class? d)Would the four methods from the general class be appropriate in the specialized class? Explain your answer. e)Give one example of a method that might appear in the specialized class but not the more general class.arrow_forwardFor each of the following two code sketches complete the following three steps: Use abstraction and information hiding to improve the design of the code sketch. Your answer should be in form of a code sketch (i.e., make the design clear by providing class names, method names, and examples of how classes and objects will be used). Do not construct an entire detailed program. Describe the negative consequences of poor use of abstraction and information hiding in each code sketch. Describe how your use of abstraction and information hiding avoids the negative consequences listed in the previous step. class Vehicle { } public enum FuelType { DIESLE, ELECTRIC, HYDROGEN, LNG, JET_FUEL } public FuelType fuelType; public void add Fuel (double amount) { if (fuelType == FuelType.DIESEL) { // code for adding diesel fuel... } else if (fuelType == FuelType.ELECTRIC) { // code for adding electric fuel... } else if (fuelType == FuelType.HYDROGEN) { // code for adding hydrogen fuel... } else if…arrow_forwardPlease answer the following questions:1. Object-oriented programming uses classes and objects. What are classes and what are objects? What is the relationship between classes and objects?2. Explain Field and method declaration with example.3. How can we access the class members?4. Explain static members and static methods.5. Explain method overloading with example.arrow_forward
