Hi,

I have a collection which is like {obj1, null, obj3}. This collection is the result of a database query.
when i am trying to access the 2nd object(which is null) i am getting NPE. How can i filter the collection for null values?

Thanks in advance.

do you want to prevent null objects from going into the collection, or when the object is null, avoid getting the NPE?


There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
