java: ArrayList - how can i check if an index exists? -

-

I ArrayList & lt; String & gt; I'm using and I add data to a specific index, I check whether a specific index exists?

Should I just get () and check the value? Or should I wait for an exception? Is there any other way?

Update

Thank you for your reply, but because I'm only adding stuff to a specific index, the length of the list will not be visible to me which are available.

method arrayList.size () number of items in the list - therefore if If the index is equal to or equal to size () , then it does not exist.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
