Using Java, solve the following problem using JavaFX:
Write a program (Call the class ImageDisplay) that displays four images in a grid pane, as shown below. You are given 4 flags for the display, but you are free to choose other images.
You are to use a GridPane for the layout. Also use ImageView.
You will need to create an object for each image and use add method of GridPane to add an image to a specified row and column layout.
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.
Please and thank you

Step 1: Implement the getSortedRunLength() method Implement the getSortedRunLength() method in NaturalMergeSorter.java. Access NaturalMergeSorter.java by clicking on the orange arrow next to NaturalMerge.java at the top of the coding window. getSortedRunLength() has three parameters: array: a reference to an array of integers, arrayLength: an integer for the array's length, and startIndex: an integer for the run's starting index. The method returns the number of array elements sorted in ascending order, starting at startIndex and ending either at the end of the sorted run, or the end of the array, whichever comes first. The method returns 0 if startIndex is out of bounds. File NaturalMerge.java has several test cases for getSortedRunLength() that can be run by clicking the "Run program" button. One test case also exists for naturalMergeSort(), but that can be ignored until step two is completed. The program's output does not affect grading. Submit for grading to ensure that the…

- Say we are about to build an ArrayList. Your ArrayList should guarantee that the array capacity is at most four times the number of elements. What would you like to do to maintain such a limit on the capacity? What is the benefit of using iterators? Can you describe your first experience of GUIs? And could you describe what is the advantage of using GUIs over Command-Line Interface (CLI) operations?arrow_forward1. Given a Vertex object x, give Java code to enumerate its outgoing edges. ("Enumerate" means "to list"; your code does not need to do anything with the edges, but should be setup code that would make it easy to do something with each edge if we wanted to add that in.) 2. Given a VertexAndDist object x and a new distance d, give Java code to create an updated object with the same vertex as x but with distance d. 3. For simplicity of implementation, we use HashMaps to map vertices to handles/parents and edges to weights. How could you modify the Vertex and/or Edge classes, as well as the maps themselves, to implement the maps using ordinary arrays, with no hashing? Be sure to address both the vertex and edge maps in your answer. (Hint: consider the Vertex's "id" field for inspiration.)arrow_forwardI am in Java class now.

You will need to import at least one package, but you do not need to import java.lang, which is the fundamental Java package (the classes you automatically get when you write Java programs). 2. Convert the first for-loop first. Don't forget you cannot use the ArrayList method to control the for-loop (so just use the number 4). 3. Convert the last for-loop next, to view the contents of your ArrayList. 4. Convert the middle for-loop last. You may want to convert the one line of array code to two lines of ArrayList code. 5. Finally, before the last for-loop, add a new element (0) to position 0 of the ArrayList. You should print the contents of the modified ArrayList.
