There's no real need to use a StringBuilder either. You can just buffer your output using a PrintWriter - something like PrintWriter out = new PrintWriter(new BufferedWriter(...));
Then you can just use out.println() and out.printf() like you would do with System.out, and the buffering will all be neatly taken care of. :) On Sep 9, 9:43 am, Paulo Rômulo <p.romu...@gmail.com> wrote: > 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.
