1B. Suppose a class has an instance variable
x and a method with a local variable x.
i. If x is used in a calculation in the body
of the method, which x is being referred
to?
ii. Suppose you needed to add the local
variable x to the instance variable x in the
body of the method. How would you do
so?

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.

- Part darrow_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_forwardExplain the concept of covariant return types in method overriding and provide an example in a programming language of your choice.arrow_forward
- Create your own UML diagram — similar to the above UML diagram — for a Pet class that meets thespecification below.1. Create the fields indicated below. Use these names exactly as given for your fields. Define them inexactly this order.• name — The name of the pet, e.g., “Rufus”, “Mittens”, “Smelly”, etc.• animal — The type of pet, e.g., “dog”, “cat”, “asparagus”, etc.• age — The (integer) number of years the pet has been alive, e.g., 1, 2, 3, etc.2. Create a mutator for each of the above in the order listed. Use the standard Java naming conventionfor mutators.3. Create an accessor for each of the above in the order listed. Use the standard Java naming conventionfor accessors.Example: Suppose you are taking the question for the example Car UML above instead of your Pet UML.Don’t enter any spaces at all.When the question asks: Enter line 1:You would enter: CarWhen the question asks: Enter line 2:You would enter: -make:StringWhen the question asks: Enter line 3:You would enter:…arrow_forwardSelect the answer that best describes the following statements: 1.

A class that implements an interface can define only the methods that are included in the interface. A static variable can be referenced only from a static method. Static variables are also called class variables.arrow_forward

Why is it important, and how does it ensure the proper behavior of derived classes?arrow_forwardQUESTION 1 Write a class Complex for complex number system. The class should have 2 fields for real and imaginary part. The class should have two methods: 1. One takes 2 complex objects and returns their addition as a new complex object. 2. Another takes 2 complex objects and returns their multiplication as a new complex object Now create driver class with arbitrary values.arrow_forwardWhat is the best reason to make a method be a static method? A. When the method does not make use of any of the class variables. B. When it includes a reference to a static variable. C. When we want to guarantee that it is a public method. D. Static methods should not be used in object oriented languages.arrow_forward
