JAVA is an object oriented programming language which was developed by  James  Gosling and his team at Sun Microsystems  in the year 1991 later acquired by oracle corporation however it is under general public license so anyone can use java platform to develop applications .

Features of JAVA :

  • Object oriented
  • Platform Independent
  • Portable
  • Secured
  • Robust
  • Architectural Neutral
  • Multithreaded
  • Distributed
  • Interpreted
  • Dynamic and etc.

All these above features make JAVA simple and it is used to develop standalone and standard software applications and also web applications.

Basically JAVA is divided into three editions they are:

  • J2SE: JAVA Standard Edition is a  computing platform which is used to develop  and deploy code for desktop and server environments.
  • J2EE: JAVA Enterprise Edition is a computing platform which is used to develop and deploy web applications online for enterprises
  • J2ME: JAVA Micro Edition is a technology that allows JAVA programmers to  use JAVA and its related tools to develop applications for mobile and wireless devices.

Objectives of JAVA training :The main objective of our JAVA course is to make students familiar with JAVA environment  making  them write code using object oriented concepts and developing applications using JDBC.

Why 4junctions:4junctions which is well known for advanced IT  courses with an aim to make entry level IT professionals employable  initiated JAVA  course where students can learn from expert faculty in a real time environment.
