- Write JavaFX code with an intuitive GUI design that can generate a Fibonacci number sequence of a certain length (e.g., 30-50 numbers) via pressing a ‘Fib Gen’ button. The program should have at least two filtering functions on the generated number sequence.Look at the API of the Point class and find out how to construct a Point object. Write a Java program “PointTester”, that constructs two points with coordinates (3, 4) and (–3, –4). Find the distance between them, using the distance method. Print the distance, as well as the expected value. (You may draw a sketch on graph paper to find the value you will expect.) - Update your program so it randomly select coordinate points (x,y), where −50 ≤ ? ≤ 50 ??? ? ∈ [−90, 90].Complete the code below to have a scaling rectangle java. public void start(Stage primaryStage) { // create a rectangle with width 50, height 80 and color blue ……………………………………………………………………………………………………………………………………………………………………………………………………………… // create the transition ……………………………………………………………………………………………………………………………………………………………………………………………………………… // set the duration of the transition as 5 seconds ……………………………………………………………………………………………………………………………………………………………………………………………………………… // make the rectangle as the node for the transition ……………………………………………………………………………………………………………………………………………………………………………………………………………… // transition to double the size of x ……………………………………………………………………………………………………………………………………………………………………………………………………………… // transition to double the size of y ……………………………………………………………………………………………………………………………………………………………………………………………………………… // set the cycle count as 2…

- A plus sign is the symbol used for addition in Mathematics. Usually, the plus sign is written as across of horizontal and vertical lines.Using OpenGL, design and code an example of a plus sign. You can make the plus signmove backward, forward, going to the top or going down with the use of arrow keys in thekeyboard. By pressing the plus sign (+), the program will enlarge or magnify the plus sign whileby pressing the minus sign (-), the plus sign will be reduced or decrease. Also, if the space key ispressed, then the plus sign will be rotated by a certain degree or angle. If the enter key is pressed,the plus sign will randomly change its color. Save your file as plussign.cpp.build a snowman in jgrasp using javafx. The snowman should move with a keyboard mouse event. left right. attach the java file.Converting an image to grayscale simplifies the algorithm and reduces computational requirements prior to extracting the image features. Write a Java program to convert a colour image to a grayscale image by manipulating the pixel colour values. The Red : Green : Blue ratio should be set to 28:60:12.
