The percentage increase in undercooling temperature of metal when dendrite fraction changes from 0.012-0.025 needs to be determined. Note that specific heat and latent heat of fusion is constant. Concept introduction: Undercooling is the process in which the temperature of a material is lowered below its freezing point without solidifying that material. Undercooling is also called as supercooling.

The output of the client code execution is given below. You'll get a similar output with different timestamps. This output displays the difference in instance creation time between the Lazy and Eager approaches. Creating three instances of Lazy Singleton... Instance created at:6:49:09:38 Instance created at:6:49:11:49 Instance created at: 6:49:13:56 Creating three instances of Eager Singleton... Instance created at: 6:49:13:60 Instance created at:6:49:13:60 Instance created at: 6:49:13:60 Copy the Main class into your project. Then, implement the LazySingletonAssignment3 and EagerSingleton Assignmentз classes. Check the client code and note that the getInstance method takes a unique number parameter to indicate which instance should be returned.

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
