Book Description

This book gets you started with essential software development easily and quickly, guiding you through Java's different facets. By adopting this approach, you can bridge the gap between learning and doing immediately. You will learn the new features of Java 9 quickly and experience a simple and powerful approach to software development. You will be able to use the Java runtime tools, understand the Java environment, and create Java programs.

We then cover more simple examples to build your foundation before diving to some complex data structure problems that will solidify your Java 9 skills. With a special focus on modularity and HTTP 2.0, this book will guide you to get employed as a top notch Java developer.

By the end of the book, you will have a firm foundation to continue your journey towards becoming a professional Java developer.

What you will learn

• Compile, package and run a trivial program using a build management tool
• Get to know the principles of test-driven development and dependency management
• Separate the wiring of multiple modules from the application logic into an application using dependency injection
• Benchmark Java execution using Java 9 microbenchmarking
• See the workings of the Spring framework and use Java annotations for the configuration
