CheckerBoard.class is not public or has no constructor
Hi
I have a java applet called CheckerBoard.java
It fails to run and it gives me errors. These errors are pasted as below and the code is pasted below that.

I am new to java programming and to Applet. I am not sure how to solve this problem. Many thanks in advance.
