"-XX:+PrintGC" - GC Logging Option for Short Messages
This section describes the garbage collection logging option, '-XX:+PrintGC', which prints a shot message after each garbage collection is done. 2022-10-01, ∼474🔥, 0💬

"-XX:+PrintGC" - Watching GC (Garbage Collection) Logs
This section provides a tutorial example on how to use the HotSpot JVM command option, -XX:+PrintGC, to watch GC (Garbage Collection) logs. JVM performs GC with a regular interval during the test run loop and has no impact on the execution time of the test code. 2022-10-01, ∼473🔥, 0💬
