Java Records vs. Lombok

Java for a lot of time has been accused and mocked for its verbosity. Even the most passionate Java developers have to admit that it felt ridiculous to declare a bean class with two attributes. If you follow the right recommendations, you end up adding not only getters and setters, but also the implementations of toString hashcode and equals methods. The final result is a chunk of boilerplate that invites you to start learning another language. 

Java
  
import java.util.Objects;

public class Car {

   private String brand;
   private String model;
   private int year;

   public String getBrand() {
      return brand;
   }

   public void setBrand(String brand) {
      this.brand = brand;
   }

   public String getModel() {
      return model;
   }

   public void setModel(String model) {
      this.model = model;
   }

   public int getYear() {
      return year;
   }

   public void setYear(int year) {
      this.year = year;
   }

   @Override
   public String toString() {
      return "Car{" +
              "brand='" + brand + '\'' +
              ", model='" + model + '\'' +
              ", year=" + year +
              '}';
   }

   @Override
   public boolean equals(Object o) {
      if (this == o) return true;
      if (o == null || getClass() != o.getClass()) return false;
      Car car = (Car) o;
      return year == car.year && Objects.equals(brand, car.brand) && Objects.equals(model, car.model);
   }

   @Override
   public int hashCode() {
      return Objects.hash(brand, model, year);
   }
}
