Learn how to automatically generate .java source files! Every Java developer eventually asks themselves "How can I auto generate Java code?" Well, I'm going to show you how in this tutorial by using a wicked library called JavaPoet. This lightweight an easy to learn API is a perfect tool to have on reserve.

In this 2 part tutorial mini-series, I'll introduce you to the core concepts to JavaPoet like TypeSpec, MethodSpec, FieldSpec; their associate builders and to JavaFile to start off with. I'll demonstrate how to generate source code for a Class, constructor, methods, javadoc, code and logic withing a method using several techniques.

We'll also cover the format placeholder specifiers like $S, $T, $N and $L which take auto generating java sourc code to the next level. Did I mention JavaPoet understands Types!
