casting Objects

[Abiodun Adisa]

I am receiving an Object from this method

public void validate(FacesContext arg0, UIComponent arg1, Object arg2)
throws ValidatorException {}

and on looking into arg2 using Debug variables i noticed it contains two ArrayList, it shows

arg2-------------------------------->Object[2]
[0]------------------------------>ArrayList<E>
[1]------------------------------>ArrayList<E>

Problem is what do i cast arg2 with in order to obtain my two ArrayList?

You would be better off to have your debugger find out what class the object belongs to. Then cast it to that class.

Thats what i did when i put a debugger on arg2 it showed Object[2] and when i expanded it i got
[0]------------------------------>ArrayList<E>
[1]------------------------------>ArrayList<E>

arg2-------------------------------->Object[2]
[0]------------------------------>ArrayList<E>
[1]------------------------------>ArrayList<E>

Object arr[] = (Object []) arg2;
ArrayList<E> firstArrayList = (ArrayList<E>) arr[0];
ArrayList<E> secondArrayList = (ArrayList<E>) arr[1];
