Object tot[ ][ ] = {{"jake","moly"},

{"larry","moses"}};

I am not very good at rows/columns but the much more correct numerical dimension.
tot.length is gonna refer to 1st dimension only. Which is 3 here.
tot[0].length is going for 2nd dimension, 2 here.
Although Java multi-D array isn't necessary rectangular/regular geometry.

tot.length will give you the number of items in the first dimension. tot[index].length will give you the number of items in the second dimension for that index.
