      int width, height, x,y,count;
      public spam(int w, int h)
      {
          width = w;
          height = h;
          count = 12;
      }

1. What is the first method to run from the program above?
   
   

2. How many classes does the program above have?
   
   

3. Why do we care tham SPAM is illegal in Virgina?

4. Name any place where a filled rectangle appears.
   
   

5. Which is more true
   a) Methods contain classes
   b) Classes contain methods
   
   

6. What type of Spam is most common in my email inbox
   a) Spam from Nigeria.

   b) Spam selling Korean toys.
   c) Spam from Hormel.
   d) Useful spam.
   
   

7. Suppose the applet has a bounding box of 500 by 500. In other words, the window containing the applet is 500 x 500. What happens if you try and draw a rectangle from 200,200 to 700, 700.

a) The program won't compile.

b) The program crashes when you run it.

c) The rectangle never appears.

d) Spam isn't about rectangles. Spam runs in circles.

e) Only those parts of the rectangle that fit within the bounding box appear.

8. Where did they get the name SPAM? Hint, it's not the food product.

9. Write me code. You can get at most 9 points.
   (1 point) Write me a program that draws a set of circles running in a diagonal from the upper left of the screen to the lower right of the screen. You must use a loop.
   (3 points) Write me a program that uses a three level heirarchy to draw two letters, each of which has two stamps on it.
   (3 points each) Finish the program at http://euclid.nmu.edu/~randy/Classes/Midterm2
