Store count of thf rows to arraylist

Hello,

I tried to count the rows of each attribute which called "wbuch", any way i use the following sql request:

Java Code:

SELECT wbuch, COUNt(*) FROM myTable  GROUP BY wbuch;

And the result was the following table:















+-------+----------+-----+















| wbuch | COUNt(*) |















+-------+-----------------+















| 12 | 15 |















| 13 | 334 |















| 15 | 20 |















| 16 | 488 |















| 17 | 16 |















| 20 | 252 |















| 21 | 24 |















| 23 | 599 |















| 30 | 599 |















| 31 | 508 |















| 33 | 599 |















| 34 | 491 |















| 35 | 571 |















| 36 | 643 |















| 37 | 152 |















| 46 | 419 |















+-------+------------------+

any way i want to store the row number's of each "wbuch" in arry list, but i didnt get it

Java Code:

public List<Integer> WbSeiten(){
        private List<Integer> wbList = new ArrayList<>();
        int rowCount = 0;
        try (Statement stmt = con.createStatement();) {
            String sql = "SELECT wbuch, COUNt(*) FROM myTable "
                    + "GROUP BY wbuch";
            ResultSet result = stmt.executeQuery(sql);
            while (result.next()) {
                rowCount =result.getInt("COUNt(*)");
                wbList.add(rowCount);
           }
        } catch (SQLException e) {
        }
        return wbList;
    }

what is wrong with my snippet ?? And how to do it correctly
