someone who said :


ArrayList my=new ArrayList(10);

works faster that ArrayList my=new ArrayList(10);

I think you meant:

ArrayList my = new ArrayList(10);
works faster than
ArrayList my = new ArrayList();

That is not true.

However:
ArrayList my = new ArrayList(100);
works faster than
ArrayList my = new ArrayList();
If you have 100 elements. However if you have only 10, then
ArrayList my = new ArrayList();
works faster.

new ArrayList() is just shorthand for new ArrayList(10).
They have exactly the same meaning.

Normally you specify the content type e.g.

ArrayList<String> my = new ArrayList<String>(100);
