A DESCRIPTION OF THE REQUEST :
ArrayList is a 1-dimensional array. To have dynamic (i.e. resizable) multidimensional arrays, a class "MultiArrayList" would be handy:

MultiArrayList mal = new MultiArrayList(2); //2 = 2 dimensions
mal.set(value1, 0, 0); //set value1 at [0,0]

As 1.5 supports varargs, the same API can be used for n-Dimensions:

MultiArrayList mal = new MultiArrayList(3); //3 = 3 dimensions
mal.set(value1, 3, 1, 7); //set value1 at [3,1,7]
Object o = mal.get(3, 1, 7); //get cell value



JUSTIFICATION :
So far, multidimensional arrays can be created via fixed arrays (e.g. new Object[][][]). But these arrays can't grow/shrink dynamically.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
ArrayList like object that supports multi dimensions.
ACTUAL -
ArrayList only supports 1 dimension (i.e. basically a List).

CUSTOMER SUBMITTED WORKAROUND :
Use standard arrays and put quite some effort to resize them via System.arraycopy(), etc.
