Quickly master, all of the concepts needed in order to build MCP servers, including transport protocols, tools, resources, prompts, roots, and sampling. Learn how to get familiar with popular MCP client applications such as, Claude Desktop, Postman, and the MCP Inspector.

Build. Deploy. Scale.Take your Java skills to the cloud-native level with Hands-On Java with Kubernetes. From your first Spring Boot or Quarkus app to production-ready deployments with CI/CD, observability, and service mesh—you’ll learn by doing, not just reading. Ideal for developers who want to master Kubernetes without getting bogged down in YAML configuration.

Stop debating code style. Start engineering code. Every developer brings personal preferences. Every AI tool channels different training examples. The result? Inconsistent codebases, endless code reviews, and technical debt that compounds silently. Java Backend Coding Technology introduces a radical idea: reduce the space of valid choices until there's essentially one good way to do most things. Not through rigid frameworks, but through a small set of patterns that make structure predictable, refactoring mechanical, and business logic visible. The code you write, your teammate writes, and your AI assistant generates will look the same -- because the patterns leave no room for subjective variation.

Book 3/3 of the Java Developers Roadmap series, this Senior Level volume dives into the advanced topics you’ll meet in real Java codebases: performance, security, code analysis, utility libraries—and modern frontiers like AI, reactive programming, and Web3. Use it as a roadmap (not a checklist) to level up your technical toolbox with clear explanations, practical examples, and common pitfalls to avoid.
