Problem 2: Multiple Shapes

For this problem you will write a program that interacts with the user to have a Turtle draw multiple shapes at locations and with the size requested by the user. You may either use the drawShape method you wrote for PSA2, write a new drawShape, or use the tashasSquare or drawRectangle method from class.

Download the CreateMultipleShapes.java file and save it in your PSA4/bookClasses directory. This file has a lot of code filled in already with several comments labeled TODO to indicate what parts you should change.

Create a World of size 800x600 and put a single Turtle in it.

Ask the user how many times they want to draw the shape. Modify the code in the CreateMultipleShapes.java to add a loop that will iterate as many times as the user requested. You may use a for loop or a while loop, but a for loop is more natural to use in this situation, since it is counter-controlled repetition.

Each iteration of the loop should

o Print out the shape number (e.g. shape number 1, shape number 2, etc.)

o Ask the user for the starting (x, y) coordinates and the size of the shape

o Move the turtle to the requested location (hint: moveTo, after putting the penUp)

o Draw the shape with the requested size (hint: remember to put the penDown)

Also complete the missing lines that are needed to get the input from the user. You MUST use the Scanner class to do this. You will need to write an import statement (before the line that starts public class), create a Scanner object that can read from the keyboard (System.in) in the initializing variables section, and complete the three lines to actually get the user input (numberShapes = , xCoordinate = , yCoordinate = , size = ). If your drawShape method has more than one parameter (e.g. drawRectangle needs width and height), add more lines to get the user input.
