IntelliJ IDEA is an Integrated Development Environment (IDE) for Java: you create Java programs in it.
You can get IntelliJ IDEA Community Edition for free. Install it at home and practice your programming skills! (“Ultimate Edition” costs money, but we don’t need its features. Get “Community Edition.”)
A good IDE has many features that make coding faster and easier. Here are just a few:
- Text editor features such as color coding and error detection
- Project file organization
- Automatic code completion and code generation
- Debugger that steps through code lines and shows variable values at each step to find bugs
It takes extra time to learn an IDE compared to using a plain text editor to create code, but a good programmer can work much faster by letting the IDE do some of the work.
