class A{}
public class B {

public static void main(String[] args) {

A[] a1 = new A[1];
A[][] a2 = new A[2][1];
a2[0] = a1;


}

}

Here a2[0] is it points to a1 array or it contains the value that a1 has ???

Multidimensional arrays are nothing more than arrays of arrays, and an array is in the end still an object. Therefore, you merely have another reference to the same array object. So yes, it points to a1 and nothing is copied.
