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.
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?

You've been challenged to implement player movement in dungeons. The game is top-down, with dungeons modeled as a 2d grid with walls at the edges. The player's location is tracked by x,y values correlating to its row and column positions. Given the current position of the player and a sequence of input commands: w,a,s,d you must determine the new position of the player. The player must not be able to move outside the walls of the dungeon (i.e. grid)Facts● the player's position is modeled using two integer values (x, y)● x represents the column position, left-right axis● top-left corner is (0,0)● y represents the row position, up-down axis● “w” move up by decreasing y by 1● “a” move left by decreasing x by 1 ● “s” move down by increasing y by 1 ● “d” move right by increasing x by 1● if an input attempts to move…arrow_forward
- In your workshop project create a new Java class (BasicArrayList) and convert the above code to work for ArrayLists. 1. 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. Here is a quick review of how array elements are modified and accessed: 1. public class BasicArray{ 2. public static void main(String[] args) int[] basic = new int[4]; for (int i=0; iarrow_forwardcan you please do this in java eclipse idearrow_forwardJava Program ASAP Please pay attention to the screenshot for test case 2 and 3 and please make sure you match the result.
