How do you create a Vector Vector in Java?

You can create a 2D Vector using the following:

  1. Vector> vector2D = new Vector>(10); This will create a Vector of size 10 which will contain Vectors with Integer(Vector) values.
  2. vector2D. add(2, new Vector(10));
  3. Vector rowVector = vector2D. get(2); rowVector.
