Task3: Rotate a Node

Add ShowImage.java to your project. Run the program. You will get errors. Why?

Because your image is not found. Download the image us.gif and save it under the directory of folder bin, where your .class files are saved. Create a new folder called image, to save all the images will be used by the program. Now your program should run correctly.

Your program can display an image using URL. Copy the following URL of an image to replace the local image:

Another image online: http://www.cs.armstrong.edu/liang/image/us.gif

Run your program.

Change code to display the three images in vertically order, instead of the current horizontal order. (HBox VBox) Why does the third image look like in the wrong position? Try to comment out the rotate method for the third image. Now run the program. Things look good. Can you conclude the reason why the third image looks in the wrong position initially?
