In case of an arraylist in Java. What will the maximum capacity of the list

Question

Now as per SCJP the arraylist max. size should be depending on the size of available memory, but list.getSize() returns an Integer. So is it safe to assume that INTEGER.MAXSIZE is the max. capacity of array . i.e int Max allowed value

Answer 1

Well, since ArrayList is backed by an array, its max capacity can't be higher than the max length of an array, which is bound by Integer.MAX_VALUE (since the index of an array is always an int).

Answer 2

There is another question with an answer matching your question and also an simple example to test: Do Java arrays have a maximum size?.

There are two limits:

1.- The available memory

2.- The max size of an Integer

But im pretty sure you hit the first before the second limit.

Hope that helps!
