- Create a class of Customer with custName, custAddress, custCnic, custPhone, custType. Create another class of Employee with empName, empAddress, empCnic, empPhone, empType (tele-callrs , doc boy, sales executive , back office). You have to provide both default and parametrized constructors.Consider a web browser where you can go back to any of the previous webpages that youhave visited earlier. However, you cannot jump directly to a previously visited page; youcan only visit them one at a time in the reverse order of how you visited them in the firstplace. State the design pattern that you would use to meet the above requirements.There shall be three classes in your design. The first class shall be named PageStorageand it contains a variable called state of the type WebPage which is the webpage thatcan be restored. The second class shall be named PageStorer which will create andstore the webpages in the PageStorage objects. The third and final class shall be namedPageList which contains a list of all the webpages that were stored, and there shall be amethod called pop() that will return the most recent webpage from the list.Draw the Class diagram. You must include all the required classes and variables andmethods mentioned above.This is the question - Create an abstract NewspaperSubscription class with fields for the subscriber name, address, and rate. Include get and set methods for the name field and get methods for the address and subscription rate; the setAddress() method is abstract. Create two subclasses named PhysicalNewspaperSubscription and OnlineNewspaperSubscription. The parameter for the setAddress() method of the PhysicalNewspaperSubscription class must contain at least one digit; otherwise, an error message is displayed and the subscription rate is set to 0. If the address is valid, the subscription rate is assigned $15. The parameter for the setAddress() method of the OnlineNewspaperSubscription class must contain an at sign (@) or an error message is displayed. If the address is valid, the subscription rate is assigned $9. Code I was given - public class DemoSubscriptions { public static void main(String args[]) { PhysicalNewspaperSubscription pnsGood = new…

- Q# A program that has no graphical user interface and only takes input through the command line only has a model and a controller. It does not have a view. The answer: is FALSE. Please explain with example. Q# What is NOT an effect of the SOLID principles? The answer: A high-level class depends on specific low-level classes and not interfaces. Please explain why. Q# Assume you are considering writing a method and are deciding what should happen when given input that is outside of perfect input. Which of the following is not a way to handle this? Answer: Use better JUnit testing. Subject: Java ProgrammingI am trying to create a class that follows these instructions. My code so far is listed at the bottom. Create a class called Game Info Use the class specification below:/*** Represents the information about a gamer on a* service like Steam, etc.** @author <put your name here>**/ GamerProfile should have the following instance variables: userName of type String pvpEnabled of type boolean online of type boolean gameLibrary of type ArrayList<GameInfo> My code: /** * Represents the information about a gamer on a * service like Steam, etc. * * @author lkelly * */ public class GamerProfile { public String userName; boolean pvpEnabled; boolean online; }Assume a class Triangle has been defined. It has three instance data, Point p1, p2, p3. The class also has a constructor that receives the 3 Points and initializes p1, p2, and p3, a toString method that outputs the 3 Points, and a computeSurfaceArea method that calculates the surface area of the Tetrahedron (as an it value). We want to extend this class to represent a 3-dimensional Tetrahedron (the Pyramid with triangle base), which consists of 4 Points. Since the Tetrahedron will consist of in essence, 4 triangles, computesurfaceArea for the Tetrahedron will compute 4 * the surface area of the Trian; made up of 3 of those 4 Points. Write the Tetrahedron class to handle the difference(s) between a Tetrahedron and the previously defined Triangle. Assume the instance data of Triangle are protected and all methods are public. Also assume that the class Point has a toString method. Write in Java only provide the stated classes, do not provide the entire code
- Is there a different way of doing this problem? Question: Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Test your class by writing a main function that creates five access…/** * A constructor that takes an existing user as well as a new userID. * It should create a new user with the newID given (which has the * same requirements as above), and the same tweets as the old user * that is being passed in. Information about the number of followers * or list of users the old user is following should not be copied. * All other instance variables should be initialized appropriately. * It may be a good idea to call the other constructor here. * * @param old the existing TwitterUser whose tweets we are copying * @param newID the ID of the new user to be created */ publicTwitterUser(TwitterUserold,StringnewID){Assume the existence of a Window class with a constructor that accepts two integer parameters containing the width and height of the window (in that order). Assume a subclass TitledWindow has been defined that has two instance variables: a string named text for the text of the title and, an integer, titleBarHeight for the height of the title bar. Write a constructor for TitledWindow that accepts four parameters: two integers containing the width and height (which are passed up to the Window constructor), and, a string and integer which are used to initialize the TitledWindow instance variables. The height of the title bar should be 'clamped' by the constructor to one half the height of the window-- i.e., if the height of the title bar passed into the constructor is greater than one half the specified height of the window, it should be set to one half the height of the window.
