How do I set this value?

I have a class:
MysqlConnect

In here I do this:

while((rs!=null) && (rs.next()))
            {
                  Item item = new Item();
                  item.setID(Integer.valueOf(rs.getString(1)).intValue());
                  item.setNamn(rs.getString(2));
                  item.setPrice(Integer.valueOf(rs.getString(5)).intValue());      
                  
                  lista.add(item);
            }

Now I want also to set  a value called Betyg. In my Items class it looks like this:
public class Item {
            private int _varuId;
            private int _pris;
            private String _namn;
            private KategoriID _kategoriId;
            private Betyg _betyg;
.....

so my problem. How do I set the Betyg in my class mysqlConnect.

My Betyg class looks like this:
public class Betyg {


      private String _text;
      private int _betyg;
      private int _varuid;
      private String _pnr;
      
.....
