Java泛型語法設置器

Question

我有這兩個類，我需要在父類的子類filds中進行初始化。

public class A { 

    protected LazyFacade<E> list; 
    protected LazyDataModel<E> model; 
    protected MyObject myObject; 

    protected LazyDataModel<E> buildModel() { 
      lazyModel = new LazyDataModel<E>() { 
       public List<E> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String, Object> filters) { 
        List<E> resultList = null; 
        try { 
         setRowCount((int) list.countObjects(myObject, filters)); 
         resultList = list.listObject(myObject, first, pageSize, sortField, sortOrder, filters); 
        } catch (PersistenceException e) { 
        } 
        return resultList; 
       } 
      }; 
     return lazyModel; 
    } 
    //getters setters 
} 

public class B extends A { 

    public B() { 
     this.list = new LazyFacade<OtherClass>(); **//is it correct way to instantiate the list???** 
     this.myObject = getObjectInDataBase(); 
     this.model = buildModel();     **//the model must have the same class of LazyFacade, in this case OtherClass. 
                //How could i do it?** 
    } 
}

嘗試改變public class A {到public class A<E> {
