Question

Really need help with this problem. And I know JavaFX but not familar with Swing.

Here is the problem:

Create, test, and document a Java program with the following classes.

Figure: This abstract class (given to you) represents a figure that can be drawn on the GUI.

Rectangle: This extends Figure and implements the functionality needed to draw filled

rectangles with a given color.

Circle: This extends Figure and implements the functionality needed to draw filled circles with

a given color.
The GUI should appear as below. (Minor deviations are fine.)

The current date should appear in the bottom left corner of the drawing. All figures appearing in the GUI should be listed with their String representations in the JTextArea appearing on the right side.

As in the video file, to draw the rectangle, the user first clicks one coordinate and then clicks the second coordinate. To draw a circle, the user first clicks the center and then the second click point is on the circumference.

When the exit button is clicked, serialize the figures and the content of the text area to disk in a file named “figures”. When the GUI is started, check for the existence of a file named “figures” and if it exists, open it to populate the figures and the corresponding list in the text area. You must not assume any specific directory structure. For example, do not write to a file named “C:Tempigures.” Instead, use “figures” to ensure that it gets stored in or retrieved from the current direc

Thanks a lot!
