In android I currently do this

    List<FishImage> newList = new ArrayList<FishImage>();
    for(FishImage image : images) {
        if (image.getApproved()) {
            newList.add(image);
        }
    }

But is there a way I could do something like which is pseudocode

List<FishImage> newList = images.getSublist(
    @Override
    public Boolean predicate(FishImage fi) {
        return fi.getApproved();
    }
);

Thanks

Nothing in the system libraries, I think. You could use a library like Guava or Commons Collections. Or just make a static helper method. – Thilo Nov 28 '14 at 01:43
How would I use `Commons Collections`? – omega Nov 28 '14 at 01:48

Im not sure how I would write the code – omega Nov 28 '14 at 01:53
