Let's look at how you declared the for loops. for (int i = 0 ; i < maze.length ; i++)
for (int j = 0 ; i < maze [1].length ; j++)Hm... the second for loop seems a wee bit off.  Change the i to j, and what's up with the one in "[1].length"?

because he seems to have a 2 - dimensional array, and he wants to find the upper bounds of the second dimension of the array, he simply has to find the upper bound of the array from an element of the first array. Recall that 2D arrays are really just an array of an arrays :P

Aside from the fact that the line in the second for loop should be j< not i
