What are the best practices for logging in Java?
Some best practices for logging in Java include using a logging framework like SLF4J, setting appropriate log levels, and avoiding logging sensitive information.
Why should I use a logging framework instead of System.out.println?
Using a logging framework allows for better control over log output, log levels, and formatting, making it easier to manage logs in production.
What log levels should I use and when?
Common log levels include TRACE, DEBUG, INFO, WARN, ERROR, and FATAL. Use TRACE and DEBUG for development, INFO for general information, WARN for potential issues, and ERROR/FATAL for serious problems.
Can you give an example of logging sensitive information?
Logging sensitive information, like passwords or personal data, should be avoided. Instead, log a message indicating that sensitive data was processed without revealing the actual data.
