What is a 'smart Java error fixer' and how does it differ from a traditional compiler?

A smart Java error fixer goes beyond basic compile-time error detection. While a traditional compiler flags syntax and type errors, a smart error fixer attempts to automatically identify and correct common, non-obvious errors, such as missing imports, incorrect variable usages based on context, and potential null pointer dereferences, leveraging static analysis and potentially machine learning. It aims to proactively resolve issues rather than just reporting them, offering suggestions for fixes and even applying them automatically (with user confirmation).
