Getting started with IntelliJ IDEA

My favourite tips for all new starters in IntelliJ IDEA

Finding code
We often need to find something in our project and there are several ways to achieve that depending on the use case.
Reading code
We spend more time reading code than writing it so it makes sense to invest effort in learning how the IDE can help us here.
Writing code
IntelliJ IDEA can help you to write code quickly and efficiently while minimising compilation errors.
Changing code
Code is rarely a write-once activity, we often need to go back and change it multiple times.
Testing code
Testing is an important part of the development workflow, irrespective of where you do it in the process.
