I have an assignment to write a java class and then a tester. I have attached the home assignment and my 2 programs when I compile the Polygon.java program I don't get any errors, but when I compile the TestPolygon.java program I get the following error:

 

 

C:UserskarisDocumentsintrotoprogramming>javac Polygon.java

 

C:UserskarisDocumentsintrotoprogramming>javac TestPolygon.java

TestPolygon.java:8: error: class, interface, or enum expected

Public class TestPolygon

^

TestPolygon.java:11: error: <identifier> expected

    Public static void main(String[] args)

       ^

2 errors

 

 

I don't know what is causing the errors.
