I have a list of objects. Each object contains another list. I want to filter the list with condition on inner list.
For example:
There is a list of factories. Each factory contains a list of different car models it produces. I want to filter factory list in such way that I will get only factories that produce Mazda3.
How can I do it with lambda?
It should be something similar to this:
factories.stream().filter(f -> f.getCars().stream().filter(c -> C.getName().equals("Mazda3")).).collect(Collectors.toList());
