java arrays

I'm trying to learn java, and the book I'm reading is now describing arrays. I get the 2d arrays pretty good, so if the code that describes the array looks something like this

int array2d [][] = {
  { 34,50,59 },
  { 40,66,70 },
  { 22,44,88 }
} ;

then I can picture that the array would be a grid that looks like this


but then the book throws 3d arrays at me, and doesn't describe it well. I was guessing that the 2d array, is like a square and a 3d array is like a cube, and if that is the case, i'm having a hard time with how the elements of the array are "addressed". For instance, in my 2d array above, the element at array[1][2] is the number 70.

and something like

System.out.println( array2d [1][2] ) ;

should show the number 70.

but for a 3d array like this

int array3d[][][] = {
  { {3,5,7} , {4,7,9} , {1,3,5},
  { {4,8,0} , {3,6,9} , {1,3,8},
  { {3,7,9} , {2,4,1} , {3,2,9}
} ;

I'm not even sure how the numbers are "addressed" let alone how I would make a

System.out.println

statement which would display the numbers I want. For instance, would the last 9 in the last column have an "address" of

System.out.println ( array3d [2] [2] [2] ) ;
