How do you study and immerse yourself in a new project?

To dive into a new Java project, I usually start by studying the documentation and technical requirements to understand the overall architecture and goals of the project. Then I examine the code structure, paying attention to the main modules and dependencies. It's important to run the project locally to see how it works in practice. It's also helpful to familiarize myself with the build system (such as Maven or Gradle) and the tests to understand coverage and logic. If possible, I communicate with colleagues to get context and recommendations. This approach helps me quickly get up to speed and start working productively.
