List records = new ArrayList(); ResultSet rs = null; try { rs = executeQuery(st); records = fetchRecords(rs, returnClass); } catch(Exception ex) { logDBError(ex); throw new DBException(ErrorCodes.DBFETCHERROR, ex); } finally { freeUp(rs); } return records; How would the about code look like with the new try-with-resources syntax? I suppose that freeUp(rs) is equivalent to rs.close(). try(ResultSet rs = executeQuery(st)) { return fetchRecords(rs, List.class); } catch(Exception ex) { logDBError(ex); throw new DBException(ErrorCodes.DBFETCHERROR, ex); }
That looks good, I was a bit worried that a catch block couldn't be attached to the new try-with-resources construct
