How do I initialize a two-dimensional List statically?

Question

How can I initialize a multidimensional List statically?

This works:

List> list = new ArrayList>();
<         


        

Answer 1

You can do so by adding a static block in your code.

private static List> list = new ArrayList>();
static {
  List innerList = new ArrayList(3);
  innerList.add(1);
  innerList.add(2);
  innerList.add(3);
  list.add(innerList);
  //repeat
}
