- Match the design pattern with its description A class that acts as a stand- in for another class. Allows you to enhance some functionality while delegating the main functionality to a (concrete) Subject. Provide the interface you want to provide for your client. Useful for hiding implementation details from your code base (e.g. if you're using a third-party library). 1. Null Object 2. Proxy 3. Decorator An object that will do nothing that is used in lieu of an uninstantiated value to prevent errors in code. 4. Adapter A way of enhancing other classes that implement the same interface. Adds functionality while delegating to an (abstract) Subject.the heart of JavaScript and jQuery is interactive web pages. When we talk about interaction what we’re referring to is some reaction or event caused by something the user did. For instance, the user clicks on something or hovers over an area and this causes a trigger of some event that then allows the user to interact further. What are the most common event handlers? There are a lot, so it may be helpful to look at their categories (i.e. mouse, document, keyboard).Computer Science Write a program to design a graphical user Interface using JavaFX without FXML and make a main class and subclasses for a project of your Interest that contains the following features add four buttons for: Add information or add service or add booking..etc Update information, update service, update booking.. etc Delete information, delete service, delete booking..etc Search information, search service, search booking..etc Add a logo at the top of the interface. You Program should follow the class Design Guidelines. Your Program should include Inheritance feature, use Interface, encapsulation. Draw a UML Diagram that represent your project. For example, Add Booking: The system will ask the user to enter the user information (Name, Phone number, Date Booked, service or anything related to your project. Once the Booking is added a message Booking confirmed with name and service, Date Booked will be displayed. The System need to check if the same Phone number…
- Please Help with Java Script eventListeners 1. Add an event listener to the button with an id of "button1". Listen for the click event. The button should change the text content of the paragraph with an id of "p1" to:"Hello World! I'm listening to events." This did NOT work://const button1 = document.querySelector("button1");//const p1 = document.querySelector("p1");//const click = () => {// alert("Hello World! I'm Listening to events.");//} //button1.addEventListener("click", p1, false); This did NOT workconst button1 = document.querySelector("button1");const p1 = button1.querySelector("p1");button1.addEventListener("click", function (event) {event.p1.target.textContent = "Hello World! I'm Listing to events.";}); 2) Add an event listener to the button with an idof "button2". Listen for the click event.

- Design and implement an application that maintains the data for a simple social network. Each person in the network should have a profile that contains the person’s name, an image(Optional), current status(Online, offline, busy,...), and a list of friends. Your application should allow a user to join the network, leave the network, create a profile, modify the profile, search for other profiles, and add and remove friends. Reference: Data Structures and Abstractions with Java, Frank M. Carrano, 4th Edition, Pearson, 2015. You can use any data structure you have learned and written so far. DO NOT USE ANY JAVA to import data structures! (Except arrays) Use your own data structures that you wrote by yourself. Use at least a hash table or a dictionary. You need at least 2 data structures: One for profiles and one for the list of the friends of those profiles. You need to implement CRUD: C= Create: Add profile- Add friends R= Read: Read the information of a profile - Search for other…Identify Testing Types c. While doing Beta testing, a customer noticed a hectic delay in the page loading ofan application.
