multidimensional array length

[Tyler Jordan]

I am having trouble getting the length of the first dimension in a multidimensional array. I have the following array.

data[x][y]

I found some info on the net saying if I want to get the first dimension's length I do:

data[x].length()

However, when I compile I get:

cannot resolve symbol
method length()

Above this part of the code I have a length method that is working fine on the same array, however I am using the following format:

data[countLine][countToken].length()

The second one that seems to work is actually calling length() on the object at the cell [x][y] which must be a String or something that has a length() method. Array doesn't have a length() method, it has a length attribute - no parens. You'd have to call the inventors of the language to ask why some things have length, others have length() and others have size().

Remembering that a multi-dimensional array is just an array of arrays ...

table.length;        <- how many subarrays we can have
table[x].length;     <- length of the subarray at x
table[x][y].length() <- length of the String in cell x, y

Cheers!
