Java Coding Standards

When reviewing or generating Java code, follow these rules:

File Naming

• Source files: PascalCase matching the public class name (e.g., UserService.java)
• One public class per file: File name must match the public class name exactly
• Test files: Class name with Test suffix (e.g., UserServiceTest.java)
• Interface files: PascalCase (e.g., Comparable.java, UserRepository.java)

Package Naming

• Packages: All lowercase, dot-separated (e.g., com.example.service, org.project.utils)
• No underscores or hyphens in package names
• Follow reverse domain name convention
