Update it to create a class Student that includes four properties: an id (type Integer), a name (type String), a Major (type String) and a Grade (type Double). Use class Student to create objects (using buttonAdd) that will be read from the TextFields then save it into an ArrayList. Perform the following queries on the ArrayList of Student objects and show the results on the listViewStudents (Hint: add buttons as needed): d) Use lambdas and streams to calculate the total average of all Students grades, then show the result. 1.

Implement a graphical application that displays a list of courses. Briefly, this GUI will take the inputs (i.e., course information), store them in an array list, and display course information in the output area. Figure 1 shows the layout ofthe CourseDisplay GUI. You should have three Java files: 1. CourseDisplayFrame class that extendsJFrame class (The main part of your program). 2.CourseDisplayViewer class, which contains the main method where a CourseDisplay object will be created, and the GUI will pop up (Suggested frame width of 450, and frame height of 400). 3.Course class, which is the class that models the Course objects (This file will be given to you). In your CourseDisplayFrame class file, you should have the followings: •Input area: –A text label and a text field (suggested width of 30) for course code; –A text label and a text field (suggested width of 30) for course name; –A text label and a text field (suggested width of 30) for course credit; –A text label and a text…
Refer to the following interface: Provide two examples (screenshots) that in many ways could improve the above or similar interface using the principles of direct manipulation. Explain the relevant improvements as well. (Examples might have different object, labels and organization)
When is the Decorator pattern applicable? When an existing operation of an object is restricted When an existing operation is enhanced When new operations need to be added to an object at runtime. All of these
Using comments within the code itself, can you provide an line by line explanation of the below JavaScript file? The file itself deals with WebGl and if that helps you.

elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate…
What is a wrapper class? A A class that wraps a border around an image in a window. B A class that encloses related classes into a package. C A class that puts the finishing touches on a GUI project by adding a "theme" of related colors and style elements. D A class that wraps a primitive data type in an object so it can be stored in a collection.
Please rewrite all of this animation code so that it performs the same functions in a java file instead of the files .css,.js, and .html (which is what I have) in visual studios. You would need to import javaFX since this would require GUI. My styles.css and Animation.html are attached as screenshots, and my script.js is below: script.js const dialogue = [ { character: 'Narrator', text: "In the dead of night, beneath a moon veiled by misty clouds, a lone figure trudged along a desolate forest path." }, { character: 'Narrator', text: "Unknown to her, she was not alone." }, { character: 'Human', text: "Who's there? Show yourself!" }, { character: 'Creature', text: "You venture into realms unknown, mortal. What brings you to these woods?" }, { character: 'Human', text: "I seek passage to the village beyond. I mean no harm." }, { character: 'Creature', text: "Harm is but a shadow in these woods, mortal." }, { character: 'Human', text: "What do you mean? Who are…

6. You are writing a game's weapon-spawning system. The weapon that's spawned is completely randomized. There are a few base types of weapons, but some of these have one or more additional functions. The additional functions can apply to any of the types of weapons. Which design pattern is the most useful here? Question options: Adapter Null Object Decorator Proxy
