    Default 2 dimensional Lists

    As we know, simple arrays can be of multi dimensions. Can an ArrayList/Vector be of 2 dimensional? Please dive code samples.

    Thanks in advance

    This can probably lead to confusing code down the road, and I would hope someone might have something better but you can try this:
    Java Code:
             ArrayList< ArrayList<String> > my_2dlist = 
                    new ArrayList< ArrayList<String> >();
             
             my_2dlist.add( new ArrayList<String>() );
             my_2dlist.get(0).add("Hello, World");
             System.out.println(my_2dlist.get(0).get(0));
