========================================
Core Java vs Adv Java vs Java Framework
========================================

==========
Core Java
==========

=> Core java means J2SE
=> Core Java is base to become java developer
=> In core java java fundamentals will be available

      - data types
      - arrays
      - strings
      - oops
      - collections
      - exception handling
      - io streams
      - lambdas
      - stream api
      - threads

-> using core java we can develop standalone apps 
  (one user can access a time)

  Ex : notepad, calc, eclipse, intellij idea....

================
Adv Java (JEE)  
================

=> JEE developed based on JSE only
=> JEE is called as Java Technology

      - Servlets
      - JSP

=> Using this JEE we can develop web applications 
   (multiple users can access at a time thru internet)

  Ex: gmail, facebook, naukri, youtube

=> To run web application  server is required
  
  Ex: Tomcat, glassfish, jboss, jetty, netty  

  1) Web Servers (Ex : Tomcat)

  2) App Servers  (ex: JBOSS, Web Logic, Web Sphere)


Note: App Server provides more functionalities than web server
  
    Ex : EJB container, security, conn pooling....  


=> Application can be developed in 2 ways

    1) Monolithic (outdated)
    2) Microservices (trending)

============
Monolithic  
============

=> Developing all the functionalities in single app

=> We have below challenges in monolithic

    1) Maintenance Difficult

    2) Single point of failure

    3) Re-Deploy entire app

    4) Technology dependent

=> To overcome problems of monolith, we are using microservices architecture.

=================
Microservices 
================

=> It is an approach to develop application functionalities with loosely coupling.

=> Application functionalities will be developed in multiple services/apis.

=> Every microservice will run in seperate server 

=> Every microservice is independently deployable and executable.

=> We have below advantages with microservices

  1) Functionality distributed

  2) Loosely coupled

  3) No single point of failure

  4) Technology independent


=================
Java Frameworks 
================= 

=> Framework is a semi developed software

=> Frameworks providing common logics for application development

=> If we use frameworks then we need to focus only on business logic

=> Using frameworks we can do more work in less time (productivity)

=> We have several frameworks in java community

      1) JSF -----------> outdated
      2) Hibernate -----> data jpa
      3) Struts -------> out dated
      4) Spring ---> SpringBoot ----> trending

Note: The above frameworks developed by using JSE and JEE.      


=> Hibernate is an ORM framework.
=> ORM means Object Relational Mapping
=> Using Hibernate we can develop persistence layer
=> Hibernate developed on top of JDBC.


=> Struts framework developed by Apache
=> Struus is used to develop only web layer

=> Spring is called as application development framework
=> Using spring we can develop entire application.
=> Spring is free of cost & open source
=> Spring framework provides common logics required for application development.

Note: SpringBoot is an extension for Spring Framework.
