🚀 Advanced Concepts

By this point, you've covered the fundamentals of the Java language, how to control the flow of a program, how objects and classes work, and how to organize data using the built-in data structures. Advanced Concepts builds on top of all of that, covering the tools that make Java code more robust, flexible, and expressive.

These concepts show up constantly in real FRC codebases: exceptions keep a single bad sensor reading from crashing the whole robot program, generics are what make every ArrayList you've already been using type-safe, lambdas and streams let you write concise logic instead of boilerplate loops and classes, and enums are the standard way to represent a mechanism's named states. None of these are required to write basic Java, but all of them are common in the kind of code you'll actually read and write on a team.
