Array reference assignments for multidimensional arrays

[Ida Achi]

A,B,E and F are the correct answers for below. Why are C and D not correct when E is correct??? Please explain to be. Thanks


Given:

public class Test {
  public static void main(String[] args) {
    short[]b = new short[4][4];
    short[][]big = new short[2][2];
    short b3 = 8;
    short b2 [][][][] = new short[2][3][2][2];

// insert code here


 }

}

Which of the following lines of code could be inserted at line /
and still allow the code to compile? (choose all that apply)

A. b2[1][1] = big;
B. b[1][0] = 3;
C. b2[0][1][]1 = b;
D. b2[0][2][1] = b[1][0];
E. b2[1][1][0][1] = b[1][0];
F. b2[1][1] =b;

The problems with C is the declaration, because, the number 1 is out of the declaration.
The problem with D is that you are trying to assign a value in a inexistent position in the array b2.

C. b2[0][1][]1 = b; ---> b2[0][1] = b;
D. b2[0][2][1] = b[1][0]; ---> b2[0][2][1][0] = b[1][0];

How does line #3

  short[]b = new short[4][4];  

work out for you. It should give an error as left of assignment operator is one dimensional array and the right hand side of the assignment operator is 2 dimensional array.

yes, I saw that, but a think it was a type error.
