How to remove an empty list from a list (Java)

Question

I have searched for this but it's in other languages like Python or R (?). I have lists inside a list and I would like to remove the empty list. For example:

[ [abc,def], [ghi], [], [], [jkl, mno]]

I would like:

[ [abc,def], [ghi], [jkl, mno]]

How do I remove empty list from a list? Thanks!

Answer 1

You could try this as well:

list.removeIf(p -> p.isEmpty());

Answer 2

You could use:

list.removeAll(Collections.singleton(new ArrayList<>()));
