Reading Code in IntelliJ IDEA.

As developers, we spend more time reading code than we do writing it. When adding new features or fixing bugs, we first have to understand existing code, so we can make the right changes in the right place.

When reading code inside the IDE, IntelliJ IDEA helps us to read and understand code by providing helpful features like syntax highlighting and inlay hints. But there are more features to help us understand a piece of code.
