Hello and Welcome to my Java 101 tutorial series. These lessons are designed to take you through the very basics of the Java language before ending off with some complex subjects. This series is aimed towards people who have never programmed before or those who have programmed but have never used Java.

Requirements

  1. Any text editor or IDE that allows you to write Java code. For these tutorials, I’m using Eclipse. If you’re more comfortable using something else, that’s cool. You can also use a cloud IDE like c9 or browxy.com (however, it doesn’t work over HTTPS. Be careful!).
  2. A good attitude!
