Gyour task is to provide the three classes: appendundomodel1, appendundoview1, and appendundocontroller1 so that they implement the corresponding interfaces. the easiest way to get started is to copy the demomodel1.java, demoview1.java, and democontroller1.java files from the demogui3 project into the src directory of the appendundogui project, rename them appropriately, and then edit them until all compiler errors are gone and their behavior matches the corresponding interfaces. note: if you cannot get everything compiling and/or working it is ok. you will get a chance to complete this task in lab with from the instructors. however, you should try to get as far as you can on your own.

4.11 painting a wall (1) prompt the user to input integers for a wall's height and width. calculate and output the wall's area (integer). note that in this case there is a new line after each prompt. (submit for 1 point). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet (2) extend to also calculate and output the amount of paint in gallons needed to paint the wall (floating point). assume a gallon of paint covers 350 square feet. store this value in a variable. output the amount of paint needed using the %f conversion specifier. (submit for 2 points, so 3 points total). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet paint needed: 0.471429 gallons (3) extend to also calculate and output the number of 1 gallon cans needed to paint the wall. hint: use a math function to round up to the nearest gallon. (submit for 2 points, so 5 points total). enter wall height (feet): 11 enter wall width (feet): 15 wall area: 165 square feet paint needed: 0.471429 gallons
