In this insightful lecture, we dive into the world of Project Lombok, a powerful tool designed to simplify and enhance Java coding practices. This tutorial will guide you through the essential Lombok annotations and how they can streamline your code, making it more readable and maintainable.

We begin by introducing Project Lombok and its significance in Java development. Understand how Lombok can transform your coding experience by reducing boilerplate code and increasing productivity.

Add Lombok

Learn how to integrate Lombok into your Java project. This section covers the steps to add Lombok as a dependency and set it up in your development environment to start leveraging its features.

Annotations

Explore the key Lombok annotations that can simplify your Java code:

• @Getter and @Setter: Automatically generate getter and setter methods for your class fields, eliminating the need for manual method creation.

• @ToString: Automatically generates a toString method, useful for debugging by printing field values.

• @NoArgsConstructor, @RequiredArgsConstructor, and @AllArgsConstructor: Generate constructors with varying numbers of arguments. @NoArgsConstructor for no arguments, @RequiredArgsConstructor for required arguments, and @AllArgsConstructor for all arguments.

• @Data: Combines @ToString, @EqualsAndHashCode, @Getter, and @Setter into one, providing a quick way to implement common methods.

• @Builder: Implements the builder pattern, facilitating object creation with optional parameters.

• @Value: Creates an immutable class with final fields and no setters, similar to @Data but focused on immutability.

• @Slf4j: Adds a logger field for your class using the Simple Logging Facade for Java (SLF4J), simplifying logging practices.

• @EqualsAndHashCode: Automatically generates equals and hashCode methods based on class fields, streamlining these crucial implementations.

Internal Working of Lombok

Understand the internal mechanisms of Lombok and how it works under the hood to generate code and integrate with your Java application. This section explains how Lombok annotations are processed to produce the final bytecode.
