# NullNotion IntelliJ Plugin
NullNotion is your ultimate companion in IntelliJ that automagically annotates fields in your entity classes with `@NonNull` or `@Nullable` based on their database constraints. No more tedious manual annotations!
## Installation
[](https://plugins.jetbrains.com/plugin/20902-nullnotion)
- **Installing from the plugin repository within the IDE:**
- Go to Preferences(Settings) > Plugins > Marketplace.
- Search for "NullNotion" and install the plugin.
- **Installing manually:**

## Features
* 🎯 Automatically annotates fields in an entity class with `@NonNull` or `@Nullable` based on database constraints.

2. Right-click on an entity Java class annotated with `@Table`, or right-click inside the class.
