But when I try to run a example program I wrote.. and I change
the extension.. I got an error stating "Can't find class Example"

okay at first I tried to compile my example program:
javac Example.java

and I got Example.class... now I change the name of the Example.class to 
Example:
mv Example.class Example

then I made the example executable:
chmod u+x Example

and then I ran it...
./Example

I got the error message saying:
"Can't find class Example"

that's what I was trying to say hehe =)

How come I get this error message?
