Error while Calling methods for objects stored inside a ArrayList

I have declared an ArrayList to store my objects of the class Books.

static ArrayList<Books> bookData = new ArrayList<Books>();

So I have multiple methods inside class Books. Let's say I have a method named... getName(), Let's assume I have objects stored inside ArrayList and I want to call the method for the object stored in the array list.

So Is this correct:

bookData[1].getName();

or

Is this correct:

bookData.get(1).getName();

If the first is wrong, then why? Is there a method to call the object stored inside ArrayList?

for Arraylist you can use only 

bookData.get(1).getName();

bookData[1].getName(); is used only with Array and Not with Arraylist

bookData[1].getName();

This is incorrect because the [1] syntax only works for an array. It does not work with an ArrayList.
