Attack complexity in your Java applications using Modular Java. This pragmatic guide introduces you to OSGi and Spring Dynamic Modules, two of the most compelling frameworks for Java modularization. Driven by real-world examples, this book will equip you with the know-how you need to develop Java applications that are composed of smaller, loosely coupled, highly cohesive modules.

The secret weapon for attacking complexity in any project is to break it down into smaller, cohesive, and more easily digestible pieces. With Modular Java, you can easily develop applications that are more flexible, testable, maintainable, and comprehensible.
