Quick and dirty:
$ perl -n -e 'print "$1\n" if /class\s+(\w+)/' AAA.java
ClassA
ClassB
This does not know anything about Java syntax and just looks for a
word after 'class' and some space. If it is in comments or you have
something like
public class
Foo {
}
it won't understand it.
More robust solutions are feasible. For example, after improving the
recent CPAN module Parse::Java, you can do a lot better. To quote
Randal, "Learn or hire".
