Vector of Vectors: Accessing a value

I would like to use a value stored in a vector of vectors as a Prepared Statement parameter.
This attempt:

Code:

---

for ( int i = 1; i < ( 10 ); i++ ) {                       
...
        pstmt.setString( 4, (String)((Vector)orderDataVector.elementAt(i)).elementAt(2) );       
...

}

---

Returns this error:
...: Method elementAt(int) not found in class java.lang.Object.
insertSpecs.setString( 4, (String)((Vector)orderDataVector.elementAt(i)).elementAt(2) ); // supplied_materials;
^
How do I fix this?

Many thanks in advance.

My BIG Mistake:

I created this problem by adding a 2-dimensional array:
String[][] orderDataVector = {.

Changing its name to String[][] orderDataArray seems to have solved the problem, allowing the use of the original code.

Many thanks for your attention to the post.

The problem in your first post was due to not casting the Object element returned from the main Vector to a Vector - i.e. you were casting the main Vector (probably not necessary), but not casting the Vector objects it contained.

I can't make sense of your second post...

Roosters they can roost also, which don't seem fair when crows can't crow,
so maybe roosters stand more show. Still, I dunno...
