title: Check if date is older than 10 years and newer than 20 years
body: <p>I am trying to check in Java 8 if a date is older than 10 years and newer than 20 years. I am using <code>Date.before()</code> And <code>Date.after()</code> and passing <code>currentDate-10</code> years and <code>currentDate-20</code> years as arguments.</p>
