Hello Friends,

I wrote a function yesterday, and defined an String array there. I
defined it like,

String[] arr = null;

No error was shown by my IDE. I thought to move ahead. But when I
tried to increase the size of my array, I was caught.

Now I learned the difference b/w Array & an Array List.

Because there is no error in this line. Initializing reference to null
is always valid.

That does not make sense. You did not allocate your array, so you
can't very well talk about increasing its size.
