Hi,
Write another get/set method is PersonForm() which returns/sets ArrayList.
This method will return addresses ArrayList.
By using getNewMethod(), get the ArrayList and Add to this.
I think you no need to setNewMethod() once again. because it will pass by
reference.
Even though you check once.
If it is not updating setNewMethod() with modified ArrayList.
private ArrayList mMyList = new ArrayList();
public Object[] getMyList() {
return mMyList .toArray();
}
public ArrayList getNewList() {
return mMyList ;
}
public void setNewList(ArrayList pCList) {
mMyList =pCList;
}
Thanks & Regards,
Ashok.D
