taking an introductory programming class for JAVA

I am taking an introductory programming class for JAVA. it first asks me to create a class named Polygon, and the create a test file name TestPolygon. i can get the class to run without errors but can not get the test to run without errors. Please look at my attached files. I named the class PolygonA because my command pormt said i needed special permission to use a class named polygon.
