Java

Finally, a Java Book Written for Actual BeginnersNo jargon. No assumptions. Just clear explanations, real examples, and practical projects. Learn Java 25 from scratch and build real applications in 12 weeks.28 chapters. 100+ examples. 50+ exercises. One complete path from "Hello World" to professional developer.

Spring Boot 4 changes everything you thought you knew about building Java applications. Virtual threads make blocking code fast again. Native images deliver instant startup. First-class API versioning finally solves the "how do we evolve our APIs?" problem. But here's the catch: upgrading isn't just a dependency bump. Jakarta EE 11, new auto-configuration patterns, GraalVM constraints, and reactive vs. virtual threads— getting it right requires understanding the *why* behind every change. This book is your production-ready guide to Spring Boot 4 and Spring Framework 7. Written for intermediate developers who need more than "hello world" tutorials. Learn how to: • Build cloud-native microservices that scale • Migrate from Boot 3 safely and incrementally • Design APIs with built-in versioning and resilience • Choose between reactive, virtual threads, and native images • Secure distributed systems with JWT and OAuth2 • Implement observability that actually helps you debug production issues 300+ pages. 27 chapters. Real code. Real architecture. Real problems solved.

Model Context Protocol (MCP) servers with Java and Spring Boot allow you to standardize how your applications connect to AI assistants and LLMs by exposing internal data and functions as structured, tool-based endpoints. By leveraging the Spring AI framework, you can easily implement MCP protocols to securely bridge your business logic with intelligent agents. This approach simplifies integration, enabling your services to be dynamically discoverable and actionable within an AI-driven ecosystem.

Write code that you can understand without holding the entire system in your head. This book shows you how Java's modern functional features—records, sealed types, lambdas, streams—combine into a powerful approach to design. You'll learn: • How to eliminate race conditions without synchronized blocks • How to write tests that test business logic, not mock frameworks • How to compose complex behaviors from simple, reusable functions • How to manage deeply nested immutable data without boilerplate • How to adopt functional patterns incrementally in existing codebases Written for working developers. Filled with production-ready code examples.

“Agentes Inteligentes en Java” te acompaña desde el primer prototipo hasta ecosistemas de agentes interoperables que hablan entre departamentos y empresas. Aprenderás a diseñar, securizar y escalar agentes en producción con guardrails, Kubernetes y protocolos A2A, todo con código Java listo para ejecutar. Es la guía definitiva para pasar de “tenemos un bot” a “operamos una red de agentes confiables que impulsa el negocio”.

You know how to code, but everyone else seems to "just get it" while you secretly Google and ChatGPT everything. The Software Realm DECODED is the patient mentor conversation you've been searching for, Peter asks the questions you're afraid to ask, and the Ultra Senior Developer explains what bootcamps skip and seniors assume you know. By the final chapter, the imposter syndrome disappears and systems finally make sense.

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.
