Frequently asked questions

AI-generated answers based on this skill's SKILL.md and metadata

What does Java skill cover for Spring Boot 3 best practices?

Java teaches Spring Boot 3.x development with enterprise architecture patterns, SOLID principles, and modern Java 17+ features. The skill covers layered code organization, RESTful APIs, proper exception handling, and testing strategies for production applications. You'll learn how to structure applications following best practices, implement dependency injection correctly, and build secure, maintainable systems.

How to write clean Java code following SOLID principles?

Java skill emphasizes writing clean, well-structured code by teaching SOLID principles with practical examples. You'll learn Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion principles applied to real Spring Boot applications. The skill demonstrates how these principles improve code maintainability, testability, and reduce technical debt in enterprise Java projects.

How does Java cover Spring Security authentication setup?

Java teaches building secure REST APIs with Spring Security, covering authentication setup, authorization patterns, and proper validation techniques. The skill shows how to implement security configurations, handle authentication flows, and validate user input to protect against common vulnerabilities. You'll learn to integrate Spring Security into layered architectures while maintaining clean code practices.

What testing strategies does Java teach with JUnit and Mockito?

Java covers comprehensive testing strategies including JUnit and Mockito for unit testing, integration testing, and test-driven development (TDD). The skill teaches how to write testable code, mock dependencies effectively, and implement testing at different layers of your application. You'll learn to build confidence in your code through proper test coverage and TDD practices.

Does Java skill compare Quarkus vs Spring Boot?

Java explores performance optimization and alternative frameworks like Quarkus alongside Spring Boot. The skill covers Java 17+ features, GraalVM native image compilation, and how Quarkus compares to Spring Boot for microservices development. You'll understand when each framework excels and how to optimize Java application performance for different deployment scenarios.

What enterprise patterns does Java cover for microservices?

Java teaches enterprise patterns essential for microservices development, including layered architecture, dependency injection, connection pooling, and caching strategies. The skill covers DTO validation, exception handling, and RESTful API design patterns. You'll learn how to apply Spring Data JPA, implement proper separation of concerns, and build scalable, maintainable microservices with Java.

Java

You are an expert in Java development with deep knowledge of Spring Boot, enterprise patterns, and modern Java features.

Core Principles

  • Write clean, efficient, and well-documented Java code
  • Follow Java 17+ features and best practices
  • Apply SOLID principles with high cohesion and low coupling
  • Use proper naming conventions (PascalCase for classes, camelCase for methods)

Spring Boot

  • Follow Spring Boot 3.x best practices
  • Use constructor injection over field injection
  • Implement proper exception handling via @ControllerAdvice and @ExceptionHandler
  • Leverage Spring Data JPA for database operations
  • Use Spring Security for authentication and authorization

Code Structure

  • Organize code in layers (controller, service, repository)
  • Use DTOs for data transfer
  • Implement proper validation with Bean Validation
  • Follow RESTful API design principles

Quarkus (Alternative)

  • Utilize Quarkus Dev Mode for faster development cycles
  • Optimize for GraalVM native builds
  • Use CDI annotations (@Inject, @Named, @Singleton)
  • Implement MicroProfile APIs
