Project Lombok is New Feature or plugin

Project Lombok is a Java library tool that generates code for minimizing boilerplate code. The library replaces boilerplate code with easy-to-use annotations.

For example, by adding a couple of annotations, you can get rid of code clutters, such as getters and setters methods, constructors, hashcode, equals, and toString methods, and so on.

We have written a lot of boilerplate code such as getter, setter, equals, hashCode methods etc. in Java for years. In some cases, this causes problems in subjects like clean and readable code.

For such situations, Project Lombok saves our eyes  . Also, you will be able to spend more time on the business logic using Lombok.

“Never write another getter or equals method again, with one annotation your class has a fully featured builder, Automate your logging variables, and much more.”

Project Lombok uses annotations to avoid boilerplate code. In the best cases, only five lines can replace hundreds of lines of code.


@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table
public class Book {
@Id
@GeneratedValue
private Long id;
private String writer;
private String name;
private String genre;
private String year;
}

Descriptions of used annotations according to JavaDoc:

  • @Data : “Generates getters for all fields, a useful toString method, and hashCode and equals implementations that check * all non-transient fields. Will also generate setters for all non-final fields, as well as a constructor.”
  • @AllArgsConstructor : “Generates a all-args constructor.”
  • @NoArgsConstructor : “Generates a no-args constructor.”
  • @Slf4j : “Causes lombok to generate a logger field.”

JDK 25: The new features in Java 25

 Java Development Kit (JDK) 25, scheduled for release in September 2025, is set to introduce several significant enhancements. Here's an overview of the notable features: 1. Stable Values API (Preview): This feature introduces stable values—objects holding immutable data treated as constants by the Java Virtual Machine (JVM). By allowing greater flexibility in initialization timing compared to final fields, stable values aim to improve application startup times. They enable performance optimizations akin to constant-folding, previously exclusive to JDK code, and ensure thread-safe, single-time initialization. This decouples the creation of stable values from their initialization without significant performance penalties.  2. Removal of 32-bit x86 Port: JDK 25 plans to eliminate both the source code and build support for the 32-bit x86 port, which was deprecated in JDK 24. Maintaining this port has become less beneficial, especially with the challenges in keeping it updated wit...
