Multidimensional arrays

Question

Is it possible to use multidimensional arrays in this playground, or am I doing it wrong. I need to use 4-dimensional and 5-dimensional arrays; maybe even 6-dimensional. For example here is how I have been doing it
Char [ ] [ ] [ ] arr = { { { a, a, a }, { ... }, { ... } }, {...} ;
System.out.println (arr [1][1][1]);

When I run it says compilation error
