Create a sub-folder named mods
within the base directory named Renderer
. This new sub-folder will replicate the directory structure that we created in the Renderer/src
(Renderer\src
in Windows) folder. We will run the Java compiler to generate a Java class file for each Java source file. A Java class file will contain Java bytecode that can be executed on the Java Virtual Machine, also known as the JVM. We will have a file with the .class
extension for each Java source file with the .java
extension, including the module descriptors. For example, after we successfully use the Java compiler to compile the Renderer/src/com.renderer.math/com/renderer/math/Vector3d.java
source file, the compiler will generate a Renderer/mods/com.renderer.math/com/renderer/math/Vector3d.class
file with Java bytecode (known as a Java class file). In Windows, we must use a backslash (\
) as the path separator instead of the slash (/
).

Overview of this book
The release of Java 9 has brought many subtle and not-so-subtle changes to the way in which Java programmers approach their code. The most important ones are definitely the availability of a REPL, known as JShell, which will make experiments and prototyping much more straightforward than the old IDE-based project-led approach. Another, more subtle change can be seen in the module system, which will lead to more modularized, maintainable code. The techniques to take full advantage of object-oriented code, functional programming and the new modularity features in Java 9 form the main subjects of this book.
Each chapter will add to the full picture of Java 9 programming starting out with classes and instances and ending with generics and modularity in Java.
