How to iterate over Vector of Vectors

How do I iterate over a Vector of Vectors in Java? I tried doing it like in C++ :

Vector<Vector<String>> elements = new Vector<Vector<String>>();
// ...
System.out.print(elements[0][0]);

But obviously that would not work.

To iterate through all the elements use a code similar to the following:

for (Vector<String> v : elements) {
    for (String s : v) {
        // Use s as you like
    }
}

To access a specific element:

int x = ...
int y = ...
...
String s = elements.get(x).get(y);
