Processing mysql records in java

I have a table with scores that contestants get after the complete a quiz. I then select the max(points) for each user and i group by user

select distinct userName, max(points) as numpoints
from tblscor开发者_如何学Pythone
group by userName 
order by numpoints desc

this gives me the order of all the highest scores for the user. i want to store these records in an array and process it, i want to rank each record plus i want to display records where the users have a tie. How can this be achieved? how will the array be set up and processed to cater for this.

1. Create a class (e.g. UserScore) with two fields - username and points
2. Get the ResultSet for the desired query (via a Statement)
3. Define a List<UserScore> list = new ArrayList<UserScore>
4. Loop the result set, using while (rs.next()) and on each iteration create a new instance of the UserScore class, set both of its fields (e.g. userScore.setPoints(rs.getInt("numpoints")), and then add the object to the list
5. If you can do with a List - go with it. If you really need an array - use list.toArray(..)

Alternatively, you can use apache commons-dbutils, and after you create the UserScore class, you just call:

List<UserScore> list = new BeanListHandler(UserScore.class).handle(resultSet);

Note that in this case your fields should be called the same way as your returned column names/aliases. You can also use the ArrayListHandler, which, instead of a list of the defined class, will give you a List<Object[]> where each column will be an element in the array.
