Mutli-Dimensional arrays

Hi all,
Thanks for fielding these questions, it's a great resource for students.
After reading the "arrays" right-up in the reference, I tried the below as a two-dimensional array. The error I get complains about syntax (unexpected token: { ) but I just can't figure out why.
Is this easily explained?
(thanks)
Jason
(a sample of the offending material)
<CODE>
int MatTower[][] = new int [13][8];
MatTower[0] = {0,0,0,0,0,0,0,0};
MatTower[1] = {3,3,6,3,0,0,0,0};
MatTower[2] = {3,3,9,0,0,0,0,0};
MatTower[3] = {6,3,3,3,3,3,3,6};
MatTower[4] = {9,0,3,3,3,3,0,9};
MatTower[5] = {3,3,3,3,3,3,0,12};
MatTower[6] = {0,20,0,3,0,0,0,0};
MatTower[7] = {15,3,0,3,0,3,0,20};
MatTower[8] = {0,0,0,12,0,0,0,0};
MatTower[9] = {0,12,0,0,0,0,0,12};
MatTower[10] = {0,8,8,0,0,0,0,8};
MatTower[11] = {0,30,0,0,0,0,0,0};
MatTower[12] = {12,0,0,12,0,0,0,12};
</CODE>

im not _sure_ but i think that the only time you can use {}'s to assign to arrays is on creation, so try and add all those either at creation (is that possible?) or try to assign them all either seperatly or in a loop, if you can

Yeah, i think Mythmon is right. Here's how you could do it:
Code:
int[][] MatTower = {
{0,0,0,0,0,0,0,0},
{3,3,6,3,0,0,0,0},
{3,3,9,0,0,0,0,0},
{6,3,3,3,3,3,3,6},
{9,0,3,3,3,3,0,9},
{3,3,3,3,3,3,0,12},
{0,20,0,3,0,0,0,0},
{15,3,0,3,0,3,0,20},
{0,0,0,12,0,0,0,0},
{0,12,0,0,0,0,0,12},
{0,8,8,0,0,0,0,8},
{0,30,0,0,0,0,0,0},
{12,0,0,12,0,0,0,12}
};

You could do it like this, too, I think...
Code:
int MatTower[][] = new int [13][8];
MatTower[0] = new int[]{0,0,0,0,0,0,0,0};
MatTower[1] = new int[]{3,3,6,3,0,0,0,0};
MatTower[2] = new int[]{3,3,9,0,0,0,0,0};
MatTower[3] = new int[]{6,3,3,3,3,3,3,6};
MatTower[4] = new int[]{9,0,3,3,3,3,0,9};
MatTower[5] = new int[]{3,3,3,3,3,3,0,12};
MatTower[6] = new int[]{0,20,0,3,0,0,0,0};
MatTower[7] = new int[]{15,3,0,3,0,3,0,20};
MatTower[8] = new int[]{0,0,0,12,0,0,0,0};
MatTower[9] = new int[]{0,12,0,0,0,0,0,12};
MatTower[10] = new int[]{0,8,8,0,0,0,0,8};
MatTower[11] = new int[]{0,30,0,0,0,0,0,0};
MatTower[12] = new int[]{12,0,0,12,0,0,0,12};
