For each warning in your code, you can either suppress or fix the warning. You suppress warnings on a case-by-case basis, leaving zero unchecked warnings in your projects. That way, any new warnings will stand out immediately.
Do you develop in Java, Python, C, VHDL or in another programming language? It doesn't matter. You can manage and suppress warnings and errors for any programming language in Eclipse.
Create a HTML report of all compiler warnings (and errors), and the reasons why they were suppressed. Track which warnings can be accepted for which reasons, and guard your code quality.
