I'm learning Java, but it feels like there are far too many syntax rules and language features to remember. Whenever I start feeling comfortable, I run into something new. How do experienced developers learn Java and decide what to memorize versus what to look up?

Make your goal solving problems, not reciting Java syntax. Once you repeatedly use things like classes, methods, loops, and conditionals, they start to feel like muscle memory. Keeping short personal notes can also help—write down concepts and examples in your own words instead of copying tutorials.
Focus on understanding concepts rather than memorizing every exact piece of syntax. Learn the fundamentals in a sensible order—data types, conditionals, loops, collections, methods, and then object-oriented programming. The syntax becomes familiar naturally through repeated use.
A structured book or course can make Java feel less overwhelming because it explains features in a clear progression and gives you examples to practice. Working through exercises by hand or typing them yourself is often more useful than just reading documentation.
The practical answer is that nobody remembers everything. Start a small project and look up whatever you need as you build it. The features you use regularly will stick, while less common library methods and syntax can simply be checked when necessary.
You’ll still want to recognize the small set of keywords and patterns you use constantly, but there’s no need to memorize the entire language.
