A Value Object is a domain concept defined by its values rather than by identity. For example, we can represent EventId, EventCode or Email as a value object. In this article, let’s explore the benefits of using value objects over primitive types.

As a Java Developer Advocate at JetBrains, I frequently demonstrate IntelliJ IDEA features through videos and articles. To do this, I usually create small demo applications focused on specific features. While this works well initially, the number of such applications grows quickly. Soon, it becomes difficult to remember which app was built for what purpose, turning it into a maintenance headache.

ChatGPT and other Generative AI tools took the world by a storm. People are using these AI tools for various purposes such as to explore a topic, to seek answers to their questions or to get help in coding, etc. ChatGPT and Google’s Gemini are very popular AI tools that are available for free with some usage limitations.

In this article, we will explore the following:

I’m a happy Lombok library user. I found this library a decade ago, and I’ve been using it ever since. I don’t remember facing any major problems with it so far.

However, I see a few people that I greatly admire and learn from often complain that Lombok is very bad, and you should avoid it. Obviously, I am curious to know what am I missing? I know a couple of scenarios where using Lombok brings some challenges. Apart from it, I really enjoy using the Lombok library.
