title: Variables declared outside init() method in servlets
body: <p>I know that for each request to a servlet a the doPost() or doGet() methods are executed and that the code wirtten inside init() method is initialised only once. But what about the code written outside all these methods?<br>
  Is that code also threaded? I mean varibles declared in that part, if they are modified in the <code>doPost()</code>, will those changes be reflected for other requsts to the servlets?</p>
