The following code pattern is present at many places in our code base. 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.DB_FETCH_ERROR, ex); }
