title: Intellij IDEA build-in inspection code vs checkstyle, PMD & findbugs
body: <p>Recently i'm looking about the best tool set to do code inspection. My IDE is Intellij 15.0 and i know there is a good inspection capabilities there but when i look over the internet i didn't found good comparison between Intellij build-in inspection code and those three.
  Can someone that tried them all can give some best practice what to use? is Intellij cover all of them?</p>
  
  <p>I know findbugs run in binary level but still let it stay in the comparison.</p>
