What is PMD known for?

PMD, which stands for Programming Mistake Detector, is primarily known for detecting common programming defects. It is a source code analysis tool that helps developers identify potential flaws in their code. This includes a wide range of issues such as unused variables, empty catch blocks, and overly complex expressions. By highlighting these defects, PMD aids in maintaining code quality and promoting best practices among programmers.

The tool operates by enforcing code standards and offering insights that can lead to more maintainable and efficient software. It supports multiple programming languages, making it versatile for projects that utilize various technologies. The focus on identifying defects ensures that developers can address issues before they become problematic, fostering a culture of thorough code review and continuous improvement within development teams.

While the other choices touch on important aspects of software development, they do not align with PMD's primary function. Runtime analysis and code distribution are typically handled by different tools specifically designed for those purposes, and while user feedback is crucial in the development lifecycle, it is outside the scope of PMD's capabilities.
