Answer:
Yes.
int[][] as; // this will define an array of arrays of integers
Multidimensional arrays, remember, are simply arrays of arrays. So a two-dimensional array of type int is really an object of type int array (int []), with each element in that array holding a reference to another int array. The second dimension holds the actual int primitives. The following code declares and constructs a two-dimensional array of type int:
int[][] myArray = new int[3][];
Notice that only the first brackets are given a size. That's acceptable in Java, since the JVM needs to know only the size of the object assigned to the variable myArray.
