Great job on implementing the AreaCalculator and Draw interfaces, as well as the various figure classes! 🎉 Your code structure is well-organized, and you've effectively utilized interfaces and enums to ensure consistency across implementations. Here are a few key points to consider for improvement:
-
Magic Numbers: Replace magic numbers with named constants to enhance code readability and maintainability. This will make your code easier to understand and modify in the future.
-
FigureSupplier Instance: Create a single instance of
FigureSupplieroutside the loop in theMainclass to avoid unnecessary instantiation. This will improve performance and readability. -
Random Figure Generation: Recalculate the
indexinside thegetRandomFiguremethod to ensure a different figure type can be returned each time, providing more variety in generated figures. -
Abstract Methods: Consider making the
calculateAreaanddrawmethods abstract in theFigureclass to enforce that subclasses provide meaningful implementations. -
Color Consistency: Return a
Colortype instead of aStringfrom thegetRandomColormethod to maintain type consistency across your application.
These improvements will help you write cleaner, more efficient code. Keep up the great work, and continue learning from these experiences! 🚀

Consider returning a Color type instead of a String from the getRandomColor method. This will ensure type consistency across the application when dealing with colors.

The calculateArea method returns 0, which might not be meaningful for a base class. Consider making this method abstract to enforce subclasses to provide their own implementation.

The draw method currently prints a generic message. Consider making this method abstract or providing a more meaningful default implementation.

The index is calculated once during the instantiation of FigureSupplier. This means getRandomFigure will always return the same type of figure. Consider recalculating index inside the getRandomFigure method to ensure a different figure type can be returned each time.

Avoid using magic numbers directly in the code. Define defaultSize, maxSize, maxBound, and any other magic numbers as constants to improve code readability and maintainability.

When creating figures, avoid passing expressions directly into constructors. Instead, assign the results of expressions to variables and pass those variables to constructors. This improves code readability.

| figures[i].draw(); | ||
| } else { | ||
| figures[i] = new FigureSupplier().getDefaultFigure(); |

Consider creating a single instance of FigureSupplier outside the loop to avoid unnecessary instantiation within each iteration. This will improve performance and readability.

| public void draw() { | ||
| String firstPart = "Figure: square, area: " + calculateArea() + " sq. units, side: "; | ||

There is a typo in the word 'unists'. It should be 'units'.
