Sort List in reverse in order

Use this:

Collections.reverse(list);

There is a method reverseOrder in the Collections class which returns a Comparator.

You can use it like Collections.sort(list, Collections.reverseOrder());

How I would do it is:

personsList.sort(Comparator.comparing(Person::getAge, Comparator.reverseOrder()));

And happy coding :)

you can reverse any type by just putting "-" or negative sign infront of your return.

Collections.sort(listed, new Comparator<Object>() {

    @Override
    public int compare(Object o1, Object o2) {

        return -o1.getLeft().compareTo(o2.getLeft());

    }
});
