 NullAway is a tool to help eliminate `NullPointerException`s (NPEs) in your Java code.  To use NullAway, first add `@Nullable` annotations in your code wherever a field, method parameter, or return value may be `null`.  Given these annotations, NullAway performs a series of type-based, local checks to ensure that any pointer that gets dereferenced in your code cannot be `null`.  NullAway is similar to the type-based nullability checking in the Kotlin and Swift languages, and the [Checker Framework](https://checkerframework.org/) and [Eradicate](https://fbinfer.com/docs/checker-eradicate/) null checkers for Java.
