array length for 2nd dimension

Hi,
Is there a way to determine the length of the second dimension in an array?
I can get the length of the first dimension no problem, but I don't know if there is a way of getting the second.
Code:int d1 =3;
int d2 =(int)random(3,6);
int[][] array = new int[d1][d2];
println("array.length = "+array.length); |

because a 2 dimensional array is really an array of arrays, in java at least, each sub-array can have its own length. its not very useful for pixel arrays or chess boards, but since arrays are just objects in java, it is strictly correct.
as a result, as far as i know, there is no "pretty" answer. the easiest way, if you know they are all of the same length, you can just ask the first one. ie
array[0].length
