New Live Stream: Making Sense of Large Java and Kotlin Classes

This month, we’ll host a live stream about techniques that can be helpful when working with large codebases. During this talk, we’ll provide you with some guidance about how to approach unknown classes both large and small, find potential issues, and solve them.

Register today and join us for the event!

Time: 4:00 pm – 5:30 pm CET



Though many developers dream of greenfield projects, in reality most of us work with projects where a fresh start is a pipe dream. If you have inherited a codebase built by other developers or are moving to a team whose codebase is unfamiliar, you inevitably end up spending time trying to understand it. Common approaches include reading source code, navigating the call graph, reading documentation, looking at UML or sequence diagrams, and even setting breakpoints to understand the code base. These techniques usually work, but is there perhaps a better way to understand small and large classes in codebases that you don’t have prior experience with?

In this live stream, we will start with the basic principles of approaching and understanding unknown classes. You will learn to ask the right questions about code, spot potential problems, and even plan your refactorings (for when you are trying to extract clusters from a large class or split classes into smaller ones).

Asking questions

We’ll be answering questions in the chat during the event. If you already know what you want to ask, feel free to submit it now as a comment on this post or you can simply ask it during the live stream.
