I have the following code in my program



The problem is that I get the NullPointerExceptions from the following lines:
this.taulukko[0] = myynti;
and
return ennustetaulukko;

The main-method is in another class that should be fine. I just don't have any clue why it gives those exceptions.

Edit: Oh, the forum messes up with italics because I had an array in my code that has index i... So I changed it.

Some italics made the post look silly. The another exception line should be:
this.taulukko[0] = myynti;
