Getting the size of a Multidimensional Array

Im currently stuck trying to get the size of the elements. It works if it in 2d 

          String[][] = new String[5][10];  

          System.out.println(test[1].length);

However lets say i have this 

          String[][][] = new String[5][10][15];
          System.out.println(test[2].length);

The above would not work. Is there anyway to get the size of the 3rd element which is 15? Edited. Thanks for your answers.

each multidimensional array is simple an array where each element contain an array.

so in case of 3 dimensional array each element has 2 dimensional array inside. and each element of it has 1 dimensional array inside. So you need to do:

 String[][][] array = new String[5][10][15];
 int length = array[0][0].length;

So saying test[2] like in your code we are referring the 2 dimensional array which is on the third position and has a size [10][15]

I imagine you would need something like test[0][0].length

Since your example is a 3D array, you want the length of the "second dimension":

System.out.println(test2[0][0].length);
