Log4j Interview Questions and Answers

Question: What is the difference between Threshold and LevelRangeFilter in log4j?
Answer:

Both Threshold and LevelRangeFilter do the same thing.

However, the threshold should be faster. Filters enable you to implement your own logic, and you can also link them together if required. If you need a basic threshold functionality, then the “threshold” function will be enough.
