Module 8: Exception Handling and Debugging
Intro to Logging Frameworks
Use SLF4J, Logback, or java.util.logging to capture diagnostics consistently.
Adopt SLF4J bindings to remain implementation-agnostic and support different appenders in production.
Structure log messages with contextual data (logger.info("Order {} failed", orderId)).
Set appropriate log levels (debug vs info vs error) to balance signal with noise.
