![]() Different integrated development environments and many other tools like generate setters and getters for us unless we forget to execute them when a new field was added.Ī setter is a method that has an argument of the same type as the field and returns void. Theory is one thing and real life is another. In my opinion, they are right and still in my professional practice I have to use a lot of classes maintaining legacy applications using legacy frameworks containing setters, getters, which are needed by the programming tools around the application. They argue that you should program with a more object-oriented mindset. Don’t make a mistake! They do not advocate to use the raw fields directly. Many developers argue that setters and getters are inherently evil and a sign of bad design. The chapter Item 16 does not mention it and even this edition still says to use private members with setters and getters for public classes, which in case of Java 9 may also mean classes in packages that the module does not export. That version of Java contains the module system. The book says that it was updated for Java 9. You can read more about it in “Joshua Bloch: Effective Java 3rd Edition” Item 16. And the same time note that it also may NOT be a tool for proper encapsulation. Note that contrary to what many juniors think creating setters and getters is not encapsulation by itself, but it may be a tool to do proper encapsulation. When a class has many fields and we want to help encapsulation we declare these fields to be private and create setters and getters, a pair for each field that can set the value for the field (the setter) and can get the value of the field (the getter). ![]() What does an accessor generatorĪccessors are setters and getters. Even though the generator is commercial grade, using the services of the framework it has simple code so that it can be represented in an article. In this article, we will look at the accessor generator, which is defined in the core module of Java::Geci and which is a commercial grade and not a demo-only generator. In the article, we created very simple hello-world generators to introduce the framework and how to generate generators generally. ![]()
