/**
Design a Geometry class with the following methods:
*
1) A static method the accepts the radius of a circle and returns the area of the circle.
Use the following formula:
Area = PI * r squared
Use Math.PI for pi and the radius of the circle for r.
*
2) A static method that accepts the length and width of a rectangle
and returns the area of the rectangle. use the following formula:
Area = Length x width
3) A static method that accepts the length of a triangle's base and the triangle's height.
The method should return the area of the triangle. Use the following formula:
Area = Base x Height x 0.5
*
*
The methods should display an error message if negative values are used for the circle's
radius, the rectangle's length or width, or the triangle's base or height.
Next, write a program to test the class, which displays the following menu and responds
to the user's selection:
