Moving to Visual Studio Code

I performed a clean install of Windows 10 on my Surface Book 2 recently and I have not installed my default go to Java IDE, which is IntelliJ. Instead I have now moved to using another tool, which I am finding is much more versatile and beneficial; Visual Studio Code. I have previously used Visual Studio Code but mainly as a way to edit my various data files such as XML, XAML, JSON, etc. and not any of my source code files like Java, C# or C++. I treated VS Code as a text editor only previously.

Visual Studio Code comes with a crazy amount of extensions which is great because that gives you options. To get started with Java, the extensions that I suggest you get is:

  • Java Extension Pack – this comes with all the necessary Java dependencies for Visual Studio Code such as proper language support for Java, Debugger for Java, Java Test Runner, Maven for Java.

On top of that extension you will need a JDK installed. If you want to know how to setup the environment for Java then have a look at the comprehensive page that Microsoft has created here. Microsoft also has a pretty sweet tutorial about how to build a Spring Boot application that can be found here.

One thing that IntelliJ made super simple was the compilation of Java code and managing all the dependencies, not to mention providing some really convenient debugging tools and project management. This makes it a really powerful development tool. When I was at university I primarily used a terminal or command console with a basic text editor for developing software, but as I moved towards writing commercial software for the company I work for I relied less and less on the terminal and command console and more on the IDE for the heavy lifting. Now that I use VS Code I am using the terminal and command console more again, and all of the necessary information such as the class path, dependencies, etc to ensure everything complies correctly is critical. Looking at this now, I really appreciate what the IDE does to simplify development process but realise how important it is to know the fundamentals.

I wrote about a similar scenario a month or so ago regarding Git (this can be found here) and how important it is to actually be really familiar with the Git commands through a terminal and/or command console because it is cross platform but it allows you to truly understand what is going on. Using a GUI is fine but all that does is issue the same commands you would use if you were using a terminal or command console. Using VS Code and the terminal to compile and execute my Java applications has allowed me to really appreciate what the IDE does to simplify the development process but also familiarise myself with the fundamentals and important concepts that can be carried between platforms.
