SpotBugs

SpotBugs is a tool that helps programmers find mistakes or potential problems in their Java code before it's used. It scans the code for patterns that could cause errors, security issues, or bugs, similar to a spell checker but for software. By identifying these issues early, developers can fix them to improve the reliability, security, and performance of their applications. Think of it as an automated quality inspector that ensures the code is clean, efficient, and less prone to problems when it runs.
