If we have this code:

int[] first;
int[] second = first;

Is second initialized by reference (that is, second points into the same
memory as first), or by value (a new copy is made)?

So

int[] second = first;

initializes by reference, while

int[] second = first[];

initializes by value?

Actually, there's no way to initialize a dynamic array by value.
