Maybe I'm using the wrong approach, but when I'm solving this kind of problem I only create a class with a main method and all the output is directed to the standard output printing a StringBuilder object that keep storing the output after each "round" of the execution in the case of a loop. As the standard output can be set to be a file, the different inputs can be treated like this:
java Main < input-small.in > output-small.out java Main < input-large.in > output-large.out java Main < input-test.in > output-test.out It's not pretty OO, but I think it's more simple. :) -- Paulo Rômulo Alves Barros MSc.
