Just as a matter of interest what's with all the finals

particularly

for (final File name : folder.listFiles())

Despite initial appearances this is indeed legal as the
assignment is made multiple times but from the same statement.

Given that the final keyword is, aside from a flag to the compiler for 
possible optimization, largely documentary, what is the point of making 
name final.

In fact what does peppering the code with finals do to make it easily 
understandable to an inexperienced developer ?
