Using an Integrated Development Environment (IDE)
An Integrated Development Environment (IDE) is a software application designed to help you write code efficiently. It enhances your programming experience by offering features such as syntax highlighting, code completion, real-time error checking and automatic indentation.
If you don’t have a preferred IDE, we highly recommend using IntelliJ IDEA Community Edition. It’s free, open-source, and available for Windows, macOS, and Linux.
In the upcoming tutorials, we’ll assume you’ll be using IntelliJ IDEA as your IDE for writing and running Java code on your computer.
