![]() ![]() Generating getters and setters for each field increases the line of code. For these fields, we have to generate getters and setters accessor methods to provide access. Suppose, we are developing a Java application for which a POJO file is required that has several private fields. The Lombok Java API includes the following packages that can be used for different purposes. While the project Lombok adds all these boilerplate codes at the compile-time in the class file instead of adding these boilerplate code in original source code. When we use IDEs to generate these boilerplate codes (getters and setters), we save ourselves from writing getters and setters manually but it actually exists in the source code that increases the lines of code, and reduces maintainability and readability. The answer is no, IDEs and Lombok do different works but are closely similar to each other. Here, a question arises that does project Lombok and IDEs do the same work? If yes, then what is the use of Lombok? ![]() It is automatically plugging into IDEs and build tools to spice up our Java application. Just by using the annotations, we can save space and readability of the source code. The project Lombok is a popular and widely used Java library that is used to minimize or remove the boilerplate code. ![]() In this section, we will discuss the project Lombok, features, Lombok package. It is a tool that spices up our Java application. To overcome this drawback, project Lombok comes into existence. The major drawback is to write lots of boilerplate code. Lombok can take care of generating these methods if a field is annotated with and Therefore, the following two code listings provide the exact same functionality.Java is the most popular object-oriented programming language but it has some drawbacks. Although developing accessor methods is easy, they generally are just boilerplate code. If you are developing a POJO, you should always provide private access directly to the class fields, while creating accessor methods-getters and setters-to read from and write to those fields. Writing a POJO can be laborious, especially if there are many fields. Primitive parameters cannot be annotated with If they are, a warning is issued and no null check is generated. This code generates the following code: public id final String employeeId) Simply apply it to a field to enforce the rule: String employeeId The check throws a NullPointerException if the annotated class field contains a null value. The annotation, which should not be confused with the Bean Validation annotation, can be used to generate a null check on a setter field. Let’s start with one of the most basic utilities that Lombok has to offer. Best of all, the library works well with popular IDEs and provides a utility to “delombok” your code by reverting-that is, adding back all the boilerplate that was removed when the annotations were added. In this article, I examine several useful features that Project Lombok provides-making code easier to read and less error-prone and making developers more productive. The library replaces boilerplate code with easy-to-use annotations. The cases mentioned above cover just a few of those where Project Lombok can be a great benefit. Project Lombok is a mature library that reduces boilerplate code. How about when you are utilizing Java objects that need to be closed after use, so you need to code a finally block or use try-with-resources to ensure that the object closing occurs? Adding finally block boilerplate to close objects can add a significant amount of clutter to your code. Getters and setters for each of the fields? Moreover, adding a constructor and a toString() method will cause even more lines of code and clutter. How many lines of code will be needed to generate Imagine that you are coding a Java application and creating a plain old Java object (POJO), a Java class with several private fields that will require getter and setter methods to provide access. ![]()
