title: How to show javadoc in VScode?
body: <p>I'm currently using Ubuntu Linux. When I used to program on windows using eclipse, I could easily open javadoc when I hover over a function or when I press control and click it. Now I'm using VS code, and I can't see javadoc for some reason. When I hover over the function (Math.ceil for example) it shows some empty code that only returns 0 <a href="https://i.stack.imgur.com/zbN7A.png" rel="nofollow noreferrer">as in the screenshot attached</a>.</p>
  <p>I've already installed java extension pack. Any solutions to this?</p>
