Regarding multidimentional array

[upstream]

Hey, how can i declare and assign a value from one, or both of of it's dimension in a multidimentional array?

starting to this:

String[][] GroupList = new String[5][5];

??

i've got a book, but it's only a quick summary =/, thanks uhm, and please give me at least an example...

You mean something like this:

	String[][] GroupList = new String[5][5];
	GroupList[0][0] = "List1 Item1";
	for (int i = 0; i < GroupList.length; i++) {
	    for (int j = 0; j < GroupList[i].length; i++) {
		GroupList[i][j] = "List" + i + " Item" + j;
	    }
	}

ok thanks po...i'll try the code later XD

On a pedantic note, Java doesn't support true multidimensional arrays. What you have there is instead a jagged array.

A multidimensional array is stored contiguously, such that, when given given the number and size of the array dimensions, any item in the array can be found using a single pointer expression.

A jagged array is a one-dimensional array of references to other arrays.
Because Java doesn't have pointers, a jagged array, for all intents and purposes, can be considered behaviourally equivalent to a multidimensional array. However, it will not exhibit the same linear performance as a true multidimensional array; the speed of accessing a jagged array is dependent on the level of nesting, since one extra indirection is required per "dimension".
On the positive side, though, they are more flexible, and can be quicker for certain tasks (such as moving columns within the array, which can be accomplished by merely swapping references).

Thanks for the note
I found a good article and I'd like to share it with everyone
