Today I have completed the Practical Java Basics Course with Real-life Examples online course from Udemy. I decided to do it as a bit of revision of the Java that I have been writing as part of my Android Development and also, to see if there was any difference when writing purely Java. The principles are the same, particularly at basic level – it covered:-

• Setting up your environment (IntelliJ) on Windows, iOS and Linux distributions (Ubuntu specifically).
• Your first Java program.
• Variables – both primitive and Object references.
• Operators, loops, control flow and code blocks.
• Methods (functions) and arrays – including multi-level arrays.

I found it useful to see how writing Java that wasn’t connected to my Android Development to see if it differed in anyway; I have always written Java with my Android apps in the past. I found that the principles were the same and in many ways it has helped me to put certain concepts in perspective and a little easier to understand. It was definitely worth doing.

I’ll carry on with the Android journey next time. I look forward to seeing you there…
