Java

Migrating from JDK 8 to a modern Java release crosses years of platform change, and the hardest failures are not always the ones that stop your application. This practical guide shows you how to find what will break, understand why, and fix it systematically using real tools, reproducible examples, and a failure catalogue built around the problems Java teams actually hit.

A high-performance data access layer must resonate with the underlying database system. Knowing the inner workings of a relational database and the data access frameworks in use can make the difference between a high-performance enterprise application and one that barely crawls.

A good software architecture should keep the cost of development low over the complete lifetime of an application. This book discusses how the Hexagonal Architecture style tries to fulfill this goal and translates the concepts into actual code to provide inspiration for software developers.

Most developers treat Hibernate as a black box that turns objects into rows. This book opens the box, shows you exactly what happens inside, and teaches you how to make it work for you at scale.

Java has changed. Have your patterns kept up?The Gang of Four wrote their landmark patterns in 1994 — when Java didn't exist, generics were a decade away, and "concurrency" meant carefully managing a handful of platform threads. Thirty years later, Java 21 through 25 has transformed the language: records replace boilerplate classes, sealed interfaces model closed type hierarchies with compiler enforcement, pattern matching eliminates entire categories of unsafe casting, and virtual threads make a million concurrent tasks not just possible but routine.Modern Java Design Patterns bridges that gap. Every classic pattern is shown first in its original form, then systematically rebuilt with the language features that exist today. The result is code that is shorter, safer, more expressive, and immediately recognisable to any team working on a modern Java codebase.
