Java

Java lint tools are not normally independent of the IDE you develop in. All the major IDE's (Eclipse, IntelliJ, Netbeans, etc. - alphabetical order) have mechanisms in place for not only checking for lint-like problems, but also for fixing them too.

Features to expect from your IDE - identification of, and correction of:

1. automatic code formatting (indentation, brace positions, line-wrapping, etc.)
2. redundant code, or impossible code
3. incomplete documentation
4. variable and function name "shadowing"
5. and much, much more.
