# Java Development Best Practices Apply these standards when writing Java code to ensure maintainability, performance, and professional quality. ## Naming Conventions Follow Oracle's Java naming conventions consistently throughout the codebase. Use PascalCase for: - Classes and interfaces: `UserService`, `OrderRepository`, `Comparable` - Enums: `OrderStatus`, `LogLevel` - Annotation types: `Override`, `Deprecated` Use camelCase for: - Methods: `getUserById`, `calculateTotal`, `isActive` - Variables and parameters: `userId`, `orderCount`, `firstName` - Non-constant fields: `private String userName` Use UPPER_SNAKE_CASE for: - Constants: `MAX_RETRY_COUNT`, `DEFAULT_TIMEOUT` - Enum constants: `OrderStatus.PENDING`, `LogLevel.WARNING` Use lowercase with dots for packages: `com.company.project.module`. Use meaningful names that reveal intent. Avoid Hungarian notation and unnecessary prefixes. ```java // Good naming examples public class OrderProcessingService { private static final int MAX_RETRY_ATTEMPTS = 3; private static final Duration RETRY_DELAY = Duration.ofSeconds(5); private final OrderRepository orderRepository; private final PaymentService paymentService; private final Logger logger; public OrderResult processOrder(OrderRequest request) { var orderId = request.getOrderId(); // Processing logic } } ``` ## Modern Java Features (JDK 17+) ### Records for Data Classes Use records for immutable data carriers.
