java - I am missing a return statement -

i building dao mill project

this class:

package dao; import interfaces.idaoproject; import datapackage.dbobject; import java.util.arraylist; import type.programma.oefening; public class daoproject extends dbobject implements idaoproject { @override public arraylist<oefening> load(oefening o) { try{ string sql = "load oefeningen set code = " + o.getcode() + " code = " + o.getcode(); openconnection(); stmt = conn.createstatement(); rs = stmt.executequery(sql); } catch(exception e){ system.out.println(e.getmessage());} } }

now gives error @ public class daoproject extends dbobject implements idaoproject { missing homecoming statement how can prepare this?

you have declared method

public arraylist<oefening> load(oefening o)

shouldn't returning arraylist?
