title: A well formed java string
body: <p>A friend had an interview question asking the following:</p>
  
  <blockquote>
    <p>Given a string comprising of the characters (,),{,},[,], determine if is well formed or not.</p>
  </blockquote>
  
  <p>In my mind I would have answered no as it is a string and so "/" character would be required to print said characters. Is this correct or am I way off base? </p>
