Course details

Java is broadly classified into Core Java, programming java using the J2EE framework and programming java using the advanced J2EE frameworks like Struts, Spring, Hibernate etc.

These are seperate modules to be learnt starting at Core Java progressively upwards. Learning frameworks allows us to build applications faster.

This core java course covers the basic OOPs concepts and how they are integrated into the programming language. It then covers other programming structures required to build basic applications.

This is a hands on course, participants will spend 75% of their time coding various examples.

Who Should Take This Course:

Developers who wish to write WORM (write once run many) hardware independent code, learn java so that their code once written, can run on any hardware / software platform. This is not true for many other higher level langauges like C, C++ or Python.

It is a true object oriented langauge with extremely advanced capabilities making it easy to build and deploy complicated applications for the Web and otherwise.

It is the language of choice on our popular platform of choice Android. People looking to become Android developers need to learn java.

Programmers willing to build Web Applications and / or integrate them with other application platforms need to learn java.
