Here is the answer,
The Java programming language does not really support multi-dimensional arrays. It does, however, supports an array of arrays. In Java, a two-dimensional array 'x' is an array of one-dimensional array. For instance :-
int x = new int;
The expression x[i] is used to select the one-dimensional array; the expression x[i][j] is ued to select the element from that array. The first element of this array will be indexed with the "0" value and the last integer will be referenced by "length-1" indexed value. There is no array assignment operator.
