Avoid over-using class variables, they are appropriate for log, DAO, service and other classes that are used in most methods.
Before (we are not sure where winnerTeamGame is coming from):
private String getDayPlaceList()
{
Game game = winnerTeamGame.getGame();
String isDayOrNight = ((getHour(game)) > 17) ? " night at " : " at ";
return (getDayOfWeek(game.getStartDate()) + isDayOrNight + game.getLocation());
}
private static String getDayPlaceList(TeamGame teamGame)
{
Game game = teamGame.getGame();
String isDayOrNight = ((getHour(game)) > 17) ? " night at " : " at ";
return (getDayOfWeek(game.getStartDate()) + isDayOrNight + game.getLocation());
}
