Hi,
As we know we can asiign a array boject to a same dimensional array object
For ex: String[] array1 = {"one","two","three"};
String[] array2 = array1;

The above looks obviously simple but is there any metho to check when the same is for a multi dimesional array reference. I get confused when we have something like this. Can someone share a methodology to solve this or tell me an easy shortcut of how to identify the correct version.

public class Test {
2. public static void main(String [] args) {
3. byte [][] big = new byte [7][7];
4. byte [][] b = new byte [2][1];
5. byte b3 = 5;
6. byte b2 [][][][] = new byte [2][3][1][2];
7.
8. }
9. }
which of the following lines of code could be inserted at line 7, and still allow the code to
compile? (Choose four that would work.)
A. b2[0][1] = b;
B. b[0][0] = b3;
C. b2[1][1][0] = b[0][0];
D. b2[1][2][0] = b;
E. b2[0][1][0][0] = b[0][0];
F. b2[0][1] = big;

Thanks in advance for letting me know how it works.

You have given the clue yourself:

As we know we can assign a array object to a same dimensional array object


Start from there, try the different possibilities and see which ones compile. Come back to ask about the ones you don't understand.
 
Don't get me started about those stupid light bulbs.
