Java comparator sort in reverse order : <p>I would like to sort from highest to lowest.</p>

<p>From lowest to highest, you would normally do:</p>

<pre><code>@Override
    public int compare(Person p1, Person p2) {
        return (p1.getAge() - p2.getAge());
}
</code></pre>

<p>This would sort people by age from lowest to highest.</p>

<p>How do I do the reverse of this?</p>
