I got the following nitpick (names are changed to not give away...) ;-)
snip------- means: cut out, not important.

>public static main( String[] args )
>ThisClass com = new ThisClass()
If you need to instantiate an inner class from within a static method, it seems that the best approach is to make the inner c
lass static.
> public String getSecond( Object o)
> {

I do not understand the remark fully: I nowhere declared
class ... ThisClass. So why it is an inner class?
It is inner implicit?
Where to put static?
On other times the compiler complains that a method used
in main has to be declared static. But the program was compiled without error (or warning) and runs perfectly.
Because I do not understand fully, I put static at all possible places, but each got an error message safe if the declaration is taken out of main.
There I need static because then it is used in static main.
I got the feeling, that nitpicking should have suggested
Take this definition out of main!??? But why should a
local variable to main become a property of the class if
learning to use ArrayList is the purpose?

Sorry, Peter. My mistake.
