A car company makes a car produce application. There are different types of models that the company builds as sedan and sport. Each model has some shared and distinguishing features. The object creation process should conduct by a central class. The second central class should not be created in the application. Choose necessary patterns, Draw the UML, and code just company class methods on paper.
I have 4 class. The first one is Customer Class and in this class there is a method nameProvide() that if id length less than 10 it throws exception. There is a field named name(str). The other class is Board Class. There are fields such as points(double), win (boolean). The third class is BoardProvide Class.A method pointProvide() that if points less than 100 it throws exception . And the last class is Total Class. In total class there are a field named boardProvide type of BoardProvide and a field ArrayList<Board>boards. I need a write a method that; 1) Firstly, must be provide name validity in the method if name is not valid it throws exception. if name pass then, need to create a Board. After creating Board, boardProvide must be check that whether points is acceptiple or not. Add boards list(with finally block). If it is greater than 100, set win to True. If its not, catch exception, set False and return. JAVA
Define the Circle2DYourLastName class that contains: Two double data fields names x and y that specify the center of the circle withgetter methods. A double data field radius with getter method. A constructor that creates a circle with specified x, y, and radius. A method findTypeOfIntersection to determine and return types ofintersection as string (contained, overlap, or separate).Design a user class that prompts the user to enter the coordinates of the center andradius of two circles and displays the type of intersection. Allow the user to repeat yourprogram using a ConfirmDialog Box.

2 part question I am using eclipse! Create a class Circle, which - has a field radius (double) It should have appropriate accessor and mutator. If the Circle instance is created without parameter, the radius should be set to 1.0. Otherwise the radius should be set to the specified value. The Circle class should have a class level (not instance level) field called Pi. Since Pi is a known constant (3.14159), this field should be a constant. This variable can be accessed directly by outside objects. This Circle class should have a getArea() method and getPerimeter() method. You need to decide their return value and access level. Note: Area = Pi * radius * radius Perimeter = 2 * Pi * Radius part 2 Create a subclass of Circle class ColoredCircle by implementing the ColoredShape interface. It should have a field color of type enum ShapeColor. ColoredShape.java ShapeColor.java ColoredCircle should have two constructors. One will takes one parameters radius and set the color to…
This must be a Universal Windows Application. Define an interface Define an interface called IMeasuringDevice. Add it to your project in its own IMeasuringDevice.cs source file (Project > Add New Item > Interface). Add the following public method declarations to your new interface: MetricValue. This method will return a decimal that represents the metric value of the most recent measurement that was captured. ImperialValue. This method will return a decimal that represents the imperial value of the most recent measurement that was captured. StartCollecting. This method will start the device running. It will begin collecting measurements and record them. StopCollecting. This method will stop the device. It will cease collecting measurements. GetRawData. This method will retrieve a copy of all of the recent data that the measuring device has captured. The data will be returned as an array of integer values. Comment your new method declarations so developers using your interface…
User: Make a class called User. Create two attributes called first_name and last_name,and then create several other attributes that are typically stored in a user profile. Makea method called desctibe_user() that prints a summary of the user's information. Makeanother method called greet_user() that prints a personalized greeting to the user.Then - Create several instances representing different users, and call both methods for each user. Admin: Write a class called Admin that inherits from the User class. Add an attribute,privileges, that stores a list of strings like "can add post”, "can delete post”, "can banuser”, and so on. Write a method called show_privileges() that lists the administrator'sset of privileges. Then - Create an instance of Admin, and call your method.
displays the entire anagram.cpp application. To indicate the phrase to be anagrammed, use a class. The class's member methods enable the phrase to be displayed, anagrammed, and rotated. The main() procedure receives a word from the user, constructs a word object with this word as an input, and uses the anagram() member function to anagram the word.
In this assignment, you will create a class that you will need for the upcoming Super Ghost project. Please do your best job on this assignment as early as possible. You will depend on the code in this assignment in your final Super Ghost Project. Create a class named MyIOManager that implements the accompanying interface IOManager. MyIOManager should adequately implement all methods in the IOManager such that it accepts and returns the defined parameters and throws the outlined exceptions correctly. When you submit your assignment to Grader Than only submit your MyIOManager.java file. Please read the programmatic documentation of the IOManager interface to gain an understanding of what each function should do. This assignment will test your knowledge of serializing and deserializing a binary file, implementing interfaces, and throwing exceptions.
