int[] a, b[];
In the above code snippet, a is a single dimensional array & b is 2 dimensional array....Am I right?

Pls correct me if I'm wrong.

Correct. "a" is an array of ints. "b" is an array of arrays of ints.

Here's an excerpt from my notes...

When declaring an Array, the identifier can appear anywhere amid the pairs of brackets denoting the dimension (but not enclosed within brackets). For example...

String s[][];
String []s[];
String [][]s;

When an Array of a given type and dimension is declared, any subsequent identifiers on that line can add dimensions -- provided that the brackets indicating the additional dimensions come after the associated identifier.

int[][]a, b, c[];

In the above declaration, a and b are both declared as 2-dimensional Arrays, while c adds a dimension to become a 3-dimensional Array.

Note, however, that in the declaration below, d is a 2-dimensional Array (an Object), while e remains a primitive int.

int d[][], e;

Why in the above declaration e is not a 2-d array ??

Yes.
 
Oh sure, it's a tiny ad, but under the right circumstances, it gets bigger.
