Remove duplicates from List using Guava

Question

How can we remove duplicates from List with the help of Guava api?

Currently I am following this:

Answer 1

with generic predicate

class DuplicateRemover implements Predicate {

    private final Set set = new HashSet<>();

    @Override
    public boolean apply(T input) {

        boolean flag = set.contains(input);

        if (!flag) {
            set.add(input);
        }

        return !flag;
    }

}
