Hello,

I couldn't get it.. what does "LHS" mean?

Which of the following code fragments will successfully initialize a two-dimensional array of chars named cA with a size such that cA[2][3] refers to a valid element?
 

1.
  char[][] cA = {  { 'a', 'b', 'c' },  { 'a', 'b', 'c' }   };
2.
  char cA[][] = new char[3][];
  for (int i=0; i<cA.length; i++) cA[i] = new char[4];
3.
  char cA[][] = { new char[ ]{ 'a', 'b', 'c' }  ,   new char[ ]{ 'a', 'b', 'c' }  };
4
  char cA[3][2] = new char[][] {  { 'a', 'b', 'c' },   { 'a', 'b', 'c' }   };
5.
  char[][] cA = { "1234", "1234",  "1234"  };

Answer here is 2 only.
Explanation
1 and 3 declare a two dimensional array alright but they create the array of size 2, 3. And cA[2][3] means we need an array of
size 3, 4 because the numbering starts from 0.
4 : You cannot put array size information on LHS.
5 : This is a one dimensional array and that too of strings. Note that a java String is not equivalent to 1 dimensional array of chars.
This leaves us with only one choice 2.

LHS = left hand side
