Describe a Component Class Design where the Facade Pattern can be applied Please develop UML Diagrams and write code in any Programming Language Imagine that you want to design a laptop simulator for a customer. To do so lets assume you create a LaptopSystemSimulator class. Lets also assume that you create three more classes that are part of the LaptopSystemSimulator. These three classes are as follows: ScreenSimulator that simulates the screen module of the laptop. Assume that it has just one public method named initializeScreen KeyboardSimulator that simulates the keyboard module of the laptop. Assume that it has just one public method named initializeKeyboard HardDiskSimulator that simulates the keyboard module of the laptop. Assume that it has just one public method named initializeHardDisk Assume that you are to provide only one public method in the class LaptopSystemSimulator that initializes the laptop. Let the name the method be initlializeLaptop This method in turn calls the methods initializeScreen initializeKeyboard and initializeHardDisk one after the other to initialize the laptop simulator. The goal here is to make the life of the customer easy so that heshe does not have to deal with the component simulator modules of the laptop. Instead heshe just needs to worry about only a single method, and that is the initlializeLaptop method of the LaptopSystemSimulator. The above situation can be addressed using a Facade pattern. Develop an UML class diagram to show the use of the design pattern in the current context. Write a Java program to implement the aforementioned classes. The program can be small enough to merely illustrate the concept of the Facade Pattern. Please develop UML Diagrams and write code in any Programming Language.
