double round robin tournament

To codify True Soft's answer,

            String roundString;
            if (round < halfRoundMark) {
                roundString = ("team " + (home + 1)
                        + " plays against team " + (away + 1));
            } else {
                roundString = ("team " + (away + 1)
                        + " plays against team " + (home + 1));
            }
            rounds[round][match] = roundString;

where

int halfRoundMark = (totalRounds/2);
