Programming Assignment #7: Higher Ground Your task/Functional Requirements: Write a program that uses a 10-by-10 array of doubles that gives the height of a terrain at different points in a grid to draw a map of the terrain. Higher elevations should be colored darker than lower elevations, and all places in the terrain below a specified water level ought to be colored blue. See the screenshot below: . Once your program displays the map, it will prompt the user to enter coordinates of where to put houses on the map. Once the user is done entering in these coordinates, your program should re-draw the map with the houses in the appropriate locations and indicate visually whether each house is underwater. Below is an example with houses at (1,3), (1,2), (8,6), and (4,7): . Methodological Requirements: The array of elevations must be declared as follows: double(10) elevationLevels = ...; You can choose the numbers to place into it, just make sure that it makes a reasonably interesting map i.e., not all squares have the same elevation, you're not using my default checkboard pattern, etc.). You will use the House class provided in Project7Starter Pack. You may add methods, instance variables, new constructors, etc., but you must use this class. Store the list of houses (as objects of the House class) input by the user in an array list (*not* an array). Hint: ArrayList Use a while loop (or a do-while loop) to enable the user to enter coordinates for as many houses as they want. Use a sentinel value (like a negative coordinate) to terminate the loop. Your code must be responsive to changes: if I change the elevation map, the list of houses, or the water level, the map should be update accordingly. Your code will be well-commented and well-organized. . Don't worry about . Filtering user input (e.g., making sure they don't punch in 5.2 or "help" for a coordinate) The exact nature of how you draw your houses. If you're an artist, great! If not, great! Do worry about: Zombies (for obvious reasons) Not a requirement, but... Have fun with this! Be creative with the graphics, print out funny messages, or maybe even add some other stuff to it. Hints: I recommend using Project7Starter Pack.zip on Moodle to get you going. You'll need to familiarize yourself with a few new classes (Color, Line 2D, etc.). Check out which classes l imported in Project7Starter Pack, and look them up in the Java API. The last several sections of Chapter 2 in our book help quite a bit when learning the ropes of drawing things on a JComponent.
