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

  • 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.
