Hello Naveen. I am following your video as as you have shown at 16:44, you are able to see the virtual capacity. However, in my case when I run in debug mode, I am not able to find it. I can only see the element that I have added to the ArrayList. I am not able to see the remaining none elements (which is the remaining virtual capacity) Please could you help me to understand how can I see the virtual capacity. I am using Eclipse IDE on Windows 10 OS.

Nice video. Default Initial Capacity or Virtual Capacity of an empty array list = 10. Once the ArrayList reaches its maximum capacity, then a new ArrayList object is created with: New Capacity = (Current Capacity * 1.5) + 1

@mohammadfarhan2290 3 жыл бұрын

Means (10 * 1.5) + 1 = 16

Hello Sir,I have one question,Why should we change the virtual capacity? what is the exact function of it?

@gauri_korde Жыл бұрын

Hi Naveen, When I'm running the same program in IntelliJ , I can see only 1 memory slot is allotted for each addition not the chunk of 10 as you showed in video. Say I add 1st value - one slot is allotted then I add 2nd value then second slot is allotted. I'm using JDK 11.
