Focus on truly understanding how Java works—don’t just memorize syntax. Practice writing clean, well-structured code, and make sure you can trace through logic step by step. Review class design, array manipulation, and common algorithms like searching and sorting. Debugging is a skill—learn from your errors. Most importantly, break down problems into smaller steps and write code that is clear, efficient, and easy to follow.
