Write a java program, MyRandArt_YI.java to create an abstract painting using the geometric functions in the StdDraw library and the random function to generate points, colors, and thickness. Note: make sure to restrict ranges for each feature.

Geometric Abstract Painting: Mary Heilmann

How to create your own colors:

setPenColor(int red, int green, int blue)
Creates an opaque RGB color with the specified red, green, and blue values.

Parameters:
red – the amount of red (between 0 and 255)
green – the amount of green (between 0 and 255)
blue – the amount of blue (between 0 and 255)

How to draw a polygon:

Write a short program with a polygon and play with it until you understand how it works.

How to change thickness:

setPenRadius(0.05)

Sets the pen size to the default size (0.002). The pen is circular, so that lines have rounded ends, and when you set the pen radius and draw a point, you get a circle of the specified radius.
