I'm learning Java, but there seem to be so many syntax rules, keywords, method calls, and language features to keep track of. Just when I feel like I understand it, I run into something new. What's the best way to learn Java without trying to memorize every detail?

Keep your own short notes instead of copying entire tutorials. A notebook or simple digital file with examples and explanations in your own words can be surprisingly useful. A well-written Java book can also help because it presents the language in a structured way and gives you examples to work through.
Pick a small project and build it while looking up whatever you need along the way. As you repeatedly use variables, loops, conditionals, classes, and methods, the syntax starts to feel automatic. The important skill is knowing what you want to accomplish and where to find the exact syntax when you forget it.
Focus on understanding the concepts and common patterns instead of memorizing every piece of syntax. You’ll naturally remember the keywords and structures you use frequently, while less common details can be looked up when needed.
Learn Java in layers: start with data types and basic expressions, then conditionals and loops, followed by collections and other data structures, and finally object-oriented programming. Practicing each topic in a real program will make it much easier to retain.
There are a few dozen core keywords and constructs worth becoming comfortable with, but even those usually stick through regular practice rather than memorization alone.
