dynamical dimensions

[blabla]

hey!
anybody any idea how it can be arranged to dynamically add dimensions to an array

this means i want to add an undefined (say n) number of dimensions to a boolean
e.g.
boolean[][][][][][].....[](n-times) = new boolean[1][1][1]....[1]

ok, i suppose its not possible?
anyway, i'ld like to implement a sort of factor analysation...

thanks,
brt

Prepare for the OutOfMemoryError.

java.lang.reflect.Array.newInstance(
Class componentType,
int[] dimensions);

you can write DynaArray class that implements with a single vector and
takes arrays of indexs an parameters.

You do the multiplications to figure out where in the single vector to
look.

Watch out. Even tiny multidensional arrays can have huge numbers of
elements and you will run out of ram.

boolean[][][][][][][][] is on Object. So if you create Object[] and put all
boolean[][][][][][][][]'s in it, you'll have "virtual"
boolean[][][][][][][][][]

thanks a lot guys,
now i have to figure out, why i want to do this...
