The above code will declare two arrays of int primitive type.

This code will declare an int array named arr1 and another int variable named arr2.

Thanks all!

[] when appears behind the type applies to all variables in this declaration,
[] when appears behind a variable only applies to that particular variable.

You can see example from Arka Guhathakurta's post.
