suggest(hint) a GC run - CLR ^ JVM

Java's gc() method is a suggestion/plea to JVM at run-time. (There's no way to force an immediate GC cycle. I often call gc() some 4000 times in a few loops to coax the GC to start.)



CLR Collect() method with Optimized mode is exactly the same.



CLR Collect() method with Forced mode would force an immediate collection. No such feature in JVM.



All of these techniques are discouraged. When are they justified?
