Checkstyle
Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard. By default it supports the Google Java Style Guide and Sun Code Conventions, but is highly configurable. It can be invoked with an ANT task and a command line program.
We had a list of suggested code formation tools, as my code was written in Java I decided to use suggested formatter GoogleJavaFormat. However, I didn't decide to pick suggested tool for Linter. I picked Checkstyle; for the reason, that SpotBugs wasn't available for JDK 22.

JavaParser
Java 1-21 Parser and Abstract Syntax Tree for Java with advanced analysis functionalities.

-
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.

Project mention: We Have Code Quality At Home: Open Source Java Code Quality Tools | dev.to | 2024-05-06
SpotBugs is an open source static anlysis tool. "SpotBugs uses static analysis to inspect Java bytecode for occurrences of bug patterns." This means that SpotBugs runs against the compiled source source code, rather than raw Java files. Because it analyses bytecode, it can catch some types of bugs that source code analysis would not catch.
