(a) Interpretation: The reason for which the aluminium is used for airplane bodies is to be explained. Concept Introduction: Aluminum is soft, non-magnetic and ductile metal which also forms an alloy by melting with copper silicon.

Question

Suppose you have the task of building a user interface framework that works on top of MS-Windows, Mac OS and Linux. It must work on each platform with the platform's native look and feel. You organize it by creating an abstract class for each type of widget. We consider the following three types: text field, push button, and list box. You need to write a concrete subclass of each of those types for each supported platform. To make this robust, you need to ensure that the widget objects created are all for the desired platform. We would like to use the Abstract Factory design pattern to implement our system. Here's an example implementation of a Main class in Java that tests the abstract factory pattern by allowing the user to select a platform, creating a factory object for that platform, and using that factory object to create and render all GUI elements for that platform❘ public class Main { public static void main(String[] args) { Scanner input new Scanner(System.in); // Ask the…

When the user selects the macOS option, here is a sample of the client code's execution: Choose a platform (1-Windows, 2-macOS, 3-Linux): 2 Rendering a macOS text field. Rendering a macOS push button. Rendering a macOS list box. Check the client output and note that you don't need to implement the GUI components. For each one, simply print the name of the component and the operating system in the terminal (similar to the examples discussed in class). TIP: You need to have 16 java files (classes, interfaces, or Abstracts). (not considering the given main class) Copy the Main class into your project and provide the following: • UML class diagram Implementation of the system

Consider the following class: import java.text. SimpleDateFormat; import java.util.Date; public class Assignment3 { public Assignment3() { SimpleDateFormat dateFormat = new SimpleDateFormat("H:mm:ss: S"); String formattedDate = dateFormat.format(new Date()); System.out.print("Instance created at:" + formattedDate); We would like to implement the Assignment3 class as a modified version of the Singleton design pattern. We will create two new classes, LazySingleton Assignment3 and EagerSingletonAssignment3, which implement both the lazy and eager Singleton design patterns. Each of these classes will hold a maximum of three instances instead of one.
