Developing high-quality Java applications requires not only knowledge of the language and its ecosystem but also an understanding of best practices and techniques that enhance code quality, performance, and maintainability. Here are some tips, tricks, and best practices for Java development:

1. Code Quality and Readability
Follow Coding Conventions: Use consistent naming conventions, code formatting, and style guidelines (e.g., Oracle's Java Code Conventions).
Write Clear and Self-Documenting Code: Use meaningful names for classes, methods, and variables. Write code that is easy to understand and maintain.
Use Comments Sparingly: Comments should explain the "why" rather than the "what" of the code. Well-written code should be self-explanatory, minimizing the need for extensive comments.
2. Object-Oriented Design
Encapsulation: Use access modifiers (private, protected, public) to restrict access to class members and ensure that the internal state of objects is not exposed unnecessarily.
Prefer Composition Over Inheritance: Favor composition to create flexible and reusable components. Use inheritance when there is a clear "is-a" relationship.
