title: Can't understand what Javadoc is
body: <p>I can't understand what 'Javadoc' is.
  I wanted to know the difference between the <code>/**  */</code> and <code>/* */</code> comments in the first place.</p>
  <p>When I saw the answer in here, It said something about HTML and <em>APIs</em> in java. It was totally confusing and I couldn't understand anything. I am just a beginner in Java, so please help me...</p>
  <p>I saw that there was absolutely <em>NO Difference</em> when I used both of them. The compiler ignored both multiline comments when it was executed.</p>
