lombok.EqualsAndHashCode

lombok.EqualsAndHashCode is a Lombok annotation that generates `equals()` and `hashCode()` methods for a class. This annotation helps to reduce boilerplate code and ensures that the `equals()` and `hashCode()` methods are implemented consistently.

To use the `@EqualsAndHashCode` annotation, you simply need to annotate your class with it. Lombok will then generate the `equals()` and `hashCode()` methods based on the fields of the class.

Here's an example:

import lombok.EqualsAndHashCode;

@EqualsAndHashCode
public class MyClass {
    private int id;
    private String name;
    // other fields and methods
}

In this example, Lombok will generate the `equals()` and `hashCode()` methods for the `MyClass` class based on the fields `id` and `name`. You can customize the behavior of these methods by providing additional options to the `@EqualsAndHashCode` annotation.

For example, you can exclude certain fields from the equality check by using the `exclude` parameter:

@EqualsAndHashCode(exclude = "name")
public class MyClass {
    // fields and methods
}

This will generate the `equals()` and `hashCode()` methods considering all fields except the `name` field.

I hope this helps! Let me know if you have any more questions.
