title: See all super classes in Java
body: <p>Say you have a class A and a class B extends A and a class C extends B.</p>
  
  <p>Is there any IDE or any sort of plug-in for any idea, where in the file C.Java, on line </p>
  
  <pre><code>Class C extends B
  </code></pre>
  
  <p>I can see something like ( and Class A ) for example like a tooltip or like a comment under the line?</p>
