Submitted by Deepthi on Sat, 11/13/2010 - 19:25

Hi,

I would like to know what is the default size of ArrayList? Also, what is the default initial capacity of an ArrayList.

Is there any method to increase the capacity of the ArrayList?

Thanks in advance.

As I understood from your question, you want to know what would be the size of ArrayList object you just created. Well, it would be 0. As you keep adding elements to ArrayList, it increases.

Regarding default initial capacity of ArrayList, it would be 10. You can use ArrayList constructor to have it increased or decreased accroding to your use.

You can also use ensureCapacity method of Java ArrayList class.

Hope this helps...
