What is the importance of the destroy() method in Servlet?

Posted in: Servlets FAQs

• The destroy() method is called only once at the end of the life cycle of a servlet. 
• This method gives your servlet a chance to close database connections, halt background threads, write cookie lists or hit counts to disk, and perform other such cleanup activities. 
• After the destroy() method is called, the servlet object is marked for garbage collection.
• It can be used to “clean up” environments such as database connections.
  

public void destroy() {
    // Finalization code...
  }
