Assignment Help:
Objectives: Create an applet, Use methods from the Graphics class , Use the Color class

General Instructions:
The java class that need to be imported into this assignment is below and it is called TrainApplet. Your jobs is to complete this class with the requirements below.
Create a new Eclipse project for this assignment and import the TrainApplet.java and train.html files into that project. Specification: Create an applet that has a train engine which moves across the window.
Complete the TrainApplet.java class by doing the following
Draw a train engine relative to a specific position so that the position of the train changes every time repaint is called. (The init method in the skeleton code that was provided sets up the animation for you. All you have to do is make sure the position changes each time the paint method is called.) Use several different methods from the Graphics class to draw the train. This means different shapes (rectangles, ovals, lines) as well as both fill and draw methods.
The position of the train should change by a small amount each time the paint method is called. When the train goes off one edge of the window, it should come back on the other edge.
Display some text in the applet window - a title, a quotation or whatever seems appropriate.
Add whatever else you want to the applet to make the picture interesting. The background should not be just the default color.
Use at least three colors in your applet. At least one of them should be a custom color. There are a number of sites on the web where you can find color samples with their RGB values.
Extra Credit (max +20)
Animate the wheels of your train engine.
Make your applet adjust appropriately when the window gets resized. For example, centered text should remain centered, the train should travel the entire width of the window, background graphics should adjust as needed.
Make the train follow a more complicated path.
Smooth out the wrapping - the train should not abruptly disappear when it reaches one side of the frame or abruptly reappear on the other side.
Documentation:

You should include javadoc comments describing the class in your code. Be sure to use the @author tag in the class comment.

You should include a plain text file called README (with no extension) that describes the overall design of your program and how to use it. See README.overview and README.example to get an idea of what is expected from your Project README files. Please also include your observations about the assignment and your experience with it.
Testing

After you upload your applet to onyx, run the applet using

appletviewer train.html

to make sure that it will run properly for the grader. Programs that will not compile or run receive an automatic zero score, so do not fail to test your program on onyx before submitting.

{
//Set square dimensions
