title: Intellij Idea propose to set final for everything if possible, why?
body: <p>I'm a bit confused, my Intellij Idea warns me if no final modifiers everywhere when possible. </p>
  
  <p>Actually final is very good option, and of course its needed in lots of cases like methods parameters, constants and ... , </p>
  
  <p>But ... </p>
  
  <p>Probably there are some really strong arguments why my local method variables should be final ?</p>
  
  <p>Could you pls help me understand a benefit of such mass <strong>final</strong>  usage ?</p>
