What is the difference between -XX:+UseParallelGC and -XX:-UseParallelGC? Most links indicate the first, but http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html mentions the second.
Thank you.
From the documentation:
So it means that
-XX:+UseParallelGCwill turn on the parallel garbage collection, and-XX:-UseParallelGCwill turn it off.
