Java area class
<p>I'm working on code for a class that asked me to write an Area class that calculates the area for the following shapes: circles, rectangles, and cylinders.</p>

<p>Area of a circle = (π)(r^2)
where π is Math.PI and r is the circle's radius</p>

<p>Area of a rectangle = (width) * (length)</p>

<p>Area of a cylinder = (π)(r^2)(h)
where π is Math.PI, r is the cylinder's base, and h is the cylinder's height</p>

<p>I also have to create an Area Test class as well and I don't know where to start.</p>
