Objects First with Java: A Practical Introduction Using BlueJ, Global Edition - David J. Barnes, Michael Kölling

Objects First with Java introduces object-oriented programming from a software engineering perspective. The text integrates BlueJ, an interactive Java development environment that visualizes class structure. BlueJ lets you create and test objects, offering a better understanding than you would from simply reading source code. Unlike traditional textbooks, the chapters are not ordered by language features but by software development concepts.  The 7th Edition reflects the latest features and capabilities of Java with new material, code examples, GUI JavaFX code samples and more. It is thoroughly updated to include all recent Java language additions, and now introduces the concepts and technologies to support teams more formally.
