JAVA can be easily learned by steps.


Before beginning on JAVA it may be beneficial to understand
about Object-Oriented Programming in general.

Main Pillars of Object-Oriented Programming
Encapsulation
Inheritance
Polymorphism

Other features of Object-Oriented Programming:
Information Hiding
Abstraction

This is the 1st Mini-Course of this Series and is about the JAVA code and its fundamentals.
This is composed of 14 Sections, and you'll learn about the code core of JAVA.
Other Sections later will include GUI components (AWT and SWING classes), Graphics,
Applets, Event Handlers, More on Exceptions, I/Os, Serialization, and other topics,
all which are also very important for a thogouh understanding of the language.

To learn the JAVA code by steps, just begin with Step 1 below,
and continue on with all the other Steps in order.
