NullAway
A tool to help eliminate NullPointerExceptions (NPEs) in your Java code with low build-time overhead
Would be cool if Java got this feature, explicit optionality at a language level a la T? is an enormous developer QoL in Kotlin and Typescript in my experience. In Java there's tools like NullAway [1] but they're a hassle.
Language-level support is leagues better than Optional/Maybe in my experience too because it keeps the code focused on the actual logic instead of putting everything in a map/flatMap railway.
