- The “Shape” class is present in JavaFX library.
- The “Shape” class as well as its subclasses is present in “javafx.scene.shape” package.
- The JavaFX library holds “Shape” class that provides features for drawing shapes.
- The subclasses present in “Shape” includes:
- Line:
- It can draw a line from a point to another.
- Circle:
- It can draw a circle with a specific center as well as radius.

Greetings.
The programming language to be used is: JAVA
Please write a GUI that implements a game, where the user has to click the buttons in the order of their numbering.
* The 9 buttons are arranged in a grid of 3 by 3. Each one has a different number from 1 to 9.
* If the user selects the correct button, it should turn green and become disabled. The score should beincremented by 1.
* If the user selects the incorrect button, it should turn red and all the buttons should become disabled.
* If the user selects the “Reset” button, all buttons should be white and become enabled, their random numbers should be reassigned and the score set to 0.
Thank you.
Overview
You need to implement three programs: Area, Divisible, and ColorGenerator.
SpecificationsYou need to implement four programs: Perimeter, EvenNumber, FormulaEval, and PickColor. For this project you are expected to use good variable names and good indentation.
Area Program - Write a program that will compute the area of a rectangle. The program willread the length and width values and display the perimeter. The following is an example ofrunning the program. The example illustrates the messages used to read data and to displaythe area.
Enter base: 7 Enter height: 5 Area is: 17.5.
ColorGenerator Program - Write a program that computes a CSS color. We define a CSScolor as a string that starts with a # character and it is followed by three pairs of 2 characters.The possible pairs of two characters will be 00 or FF. A color is defined by two characters forred, two characters for green, and two characters for blue. For example, #FF0000 is…
