Building our First Application

First we need to setup our IDE - Whilst Mosh used IntelliJ on his video I decided to setup VS Code.

Starting a new Java Project

You can also create a Java project using the Java: Create Java Project command. Bring up the Command Palette (Ctrl+Shift+P) and then type java to search for this command. After selecting the command, you will be prompted for the location and name of the project. You can also choose your build tool from this command.

From here you can add classes packages and functions through the Java Projects explorer in the bottom right panel of the IDE.
