- [Instructor] We already talked about the significant amount of boilerplate code you have to write at Java programs. Groovy auto-generates getter and setter methods at runtime so you don't have to write them yourself. Groovy comes with annotations for different use cases that reduce code even more. I want to demonstrate the use of these annotations, so called AST transformations. Let's get started. We'll bring back the example project containing the Person class. In the main method, we put code into place that renders the string representation of an instance. We also compare two instances and create new instances with the help of a constructor. You can see in the Person class that all relevant boilerplate code has been added to support the functionality. An IDE can help immensely with generating the code. Let's run the existing code first by pressing the Play button to ensure that everything works as expected. As you…
