Cookie
  1. Cookie will create on Browser.
Session  
  1. Unique Session will be created for each browser if application has session object.
  2. Create on Server.
  3. Pass session id to the browser’s session scope.
  4. Browser will keep session id in browser’s session scope.
  5. When browser is closed session will be closed.
Request and Response object
  1. Request and Response objects are created for each http request and response.
Servlet
  1. One servlet object will create different thread will be used to access for servlet for different users.( But session objects will be created for each Users (for each Browser))
Context

  1. Can be accessed for every user (every Browser)









































HTTP is a stateless protocol  

Because a stateless protocol does not require the server to retain session information or status about each communications partner for the duration of multiple requests. HTTP is a stateless protocol, which means that the connection between the browser and the server is lost once the transaction ends.

Observer Design Pattern & RxJava & @Async

  Observer Design Pattern According to GoF definition,  observer pattern  defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. It is also referred to as the  publish-subscribe pattern . In observer pattern, there are many observers (subscriber objects) that are observing a particular subject (publisher object). Observers register themselves to a subject to get a notification when there is a change made inside that subject. A observer object can register or unregister from subject at any point of time. It helps is making the objects objects  loosely coupled . 1. When to use observer design pattern As described above, when you have a design a system where multiple entities are interested in any possible update to some particular second entity object, we can use the observer pattern The flow is very simple to understand. Application creates the concrete subject object. All...

                             COMPOSITION TUTORIAL The term  composition  is not unique to Java, composition is a concept of object-oriented programming. By now you should be familiar with the concept of  inheritance  - inheritance requires the use of the Java keywords  extends  or  implements . When your class inherits members from either a superclass or a superinterface, you can directly invoke or access those members. Consider the following code that demonstrates inheritance: class OperatingSystem {      void bootUp() { ... }      void shutDown() { ... } } class Computer extends OperatingSystem { } class TestMe {      public static void main(String args[]){          Computer c = new Computer();          c.bootUp();  ...
