What does int[] point to?

Question

Or what is its value exactly?

This pertains to a question about this code:

private static int[] x;

   public static void main(String[] args)
   {
      System.out.print(x[0]);
   }

Which does not compile (obviously).

The value of `x` in your `main` method is `null`. Trying to dereference it in order to access the element at index `0` causes a `NullPointerException`. — Sotirios Delimanolis, Sep 21 '15 at 19:26

The value of x is null.

It gives a NullPointerException when you do:

System.out.print(x[0]);
