Solve the task using OOP principles

Task:

There are some figures of the following types: square, rectangle, right triangle, circle, isosceles trapezoid. You need to create corresponding classes for them(Square, Rectangle, RightTriangle, Circle, IsoscelesTrapezoid)

All figures have

• state - all figures have color, but each figure type can also have one or several unique properties (radius for circle, firstLeg and secondLeg for right triangle, and so on).
• behaviour - we can obtain the area of any figure and are able to draw it. To 'draw' means to print out all information about a figure using System.out.println() (you shouldn't override toString() method for this).

Think where you should declare these fields and methods: top level class / interface / bottom level classes.

In the main() method we need to create an array of figures (the size of array can be 3 or 6, it doesn't matter). The first half of figures in this array should be generated with random parameters.

For this purpose create two more classes:

• ColorSupplier with public String getRandomColor() method - for generating random color,
• and FigureSupplier with public Figure getRandomFigure() method - for generating figure with random properties.

The other half of figures should have the same, default parameters.

For this purpose create a new method in the FigureSupplier class:

• public Figure getDefaultFigure() - this method should always return white circle with radius 10.

After generating the array, we need to display the entire list of objects that we have, for example:

 Figure: square, area: 25.0 sq.units, side: 5 units, color: blue
 Figure: triangle, area: 12.5 sq.units, firstLeg: 7 units, secondLeg: 5 units, color: yellow
