Spring is here. This is the time to go on a road trip to look at the scenery of Washington state. Unfortunately, this class doesn't incluce such a field trip! But we can still get a taste of our beautiful state by drawing a countryside scene with a Java program.

Overview

In this project, you will complete several classes to draw a picture in a graphics window. The purpose of this assignment is to give you experience writing classes in Java and using Eclipse.

To do

Download the four files AppleTree.java, Car.java, CountrysideScene.java,and Mountain.java and include them in an Eclipse project (as we did in class). Run the program by instantiating the class CountrysideScene. You should get a window that displays a blue sky, a green expanse and two mountains in the upper left corner of the image. Notice that the two mountains don't have the same size. Read through the code of CountrysideScene and Mountain. You will see that when CountrysideScene is instantiated, a graphics window is created. Then two Mountain objects are created. As it is, the draw method of the Mountain class draws a triangle in the graphics window. Make sure that you understand how this is happening within the code.

None of the classes given to you are complete. Your assignment is to complete the four classes given above and create a fith class so that an instance of CountrysideScene appears as a picture containing four different scenery elements. Here is a list of the requirements of the assignment :

• Your picture should have 4 types of elements. 3 of them must be an apple tree, a car, and a snowcapped moutain. The fourth one is up to you.
• Create a class for each type of element. The class should at least contain a constructor and a private draw method. Don't change the signature of the constructor. Keep it as
  public ClassName(int x, int y, double scale, GWindow window)
  to mean create an object of type ClassName at location (x,y) in the GWindow window with size given by the default size times scale (e.g. the height of the mountain is set by default to 100. Then a scale of 1.5 would draw a mountain with a height of 100*1.5 = 150).
  Don't do the drawing within the constructor. Instead call a private method such as draw. We will see the advantage of using a draw method in our next homework assignment. Read through the Mountain class. It contains code to give you a better idea of what to do.
• Complete the class CountrysideScene to create a picture with all of the elements in a graphics window. In the picture, each type of element should appear several times at different locations with different sizes. For the car, randomly choose between the car facing left and facing right as explained in class (see the location of the headlights on the car).
• The graphics elements should show some complexity. A single rectangle is not a good drawing for a car.
• The program should be correctly documented (use the same format as in the sample (javadoc comments /** and */)).

To create the graphics elements, you may want to draw them first on a piece of graph paper. It will make it easy for you to locate each point of your drawing with respect to some reference point (x,y).

If you want to create your own colors, use the Color constructor. It reads Color(r,g,b) where r,g and b are integers between 0 and 255. The color is a mixture of red, green and blue as specified by r, g and b. This site gives the rgb values for different colors. For example

Color 
myColor = new Color(152, 251, 152); // a pale green color

Good luck!

Here is a possible picture (shown with only three types of elements. You have to put in a fourth one as well).

 

Your program has to be your own.
