问题 In Struts 2 application we use log4j for logging. I want to log only warn but when i try to use in my log4j.properties log4j.rootLogger=warn, stdout it prints error and fatal log too.

问题 Note: I've read the apple documentation and studied a swift book. I'm confused on the difference between a "type instance method" (if such exists, correct me if I'm wrong) and a type method? Difference between class method and instance method? Difference between type property and instance property(if such exists, sorry I'm very confused on Type Properties subject)? Lastly, Do class properties exist in swift? Sorry for the confusion :'( 回答1: In Swift, types are either named types or compound
