Introduction

We love Programming. Our aim with this course is to create a love for Programming.

Java is one of the most popular programming languages. Java offers both object oriented and functional programming features.

We take an hands-on approach using a combination of JShell(An awesome new feature in Java 9) and Eclipse as an IDE to illustrate more than 200 Java Coding Exercises, Puzzles and Code Examples.

In more than 250 Steps, we explore the most important Java Programming Language Features
