How can I learn Java without relying too heavily on searches or AI?

Looking up Java syntax and language features is completely normal, even for professional developers. The important distinction is whether you’re checking how to express your own solution or searching for a complete solution to the assignment. Try to work out the algorithm and steps yourself first, then consult Java documentation or a textbook to translate those steps into Java. Avoid pasting the assignment into an AI tool and asking it to solve the problem, especially if your course has rules against that.

Take notes while studying and build a small personal reference for Java syntax, common library methods, Javadocs, and testing patterns. When you read a problem, treat it as a planning exercise: identify the inputs and outputs, break the task into smaller steps, and write pseudocode before touching Java. Your Python experience can help here because Python is often close enough to pseudocode to express the logic clearly. After the plan is solid, use your notes and a Java reference to implement it.

The main thing you’re missing is probably Java’s vocabulary and grammar, not programming ability. That comes with practice. Try solving small exercises without constantly switching to a search engine, then look up only the specific syntax or API detail that blocks you. Over time, you’ll remember the patterns you use often, while still getting comfortable with checking documentation when needed.
