What is meant by gc, prallel gc, full gc and explain it?

Answer Posted / Sakshi Singh

Garbage Collection (GC) in JVM is the automatic process of freeing up memory occupied by objects that are no longer being used. Parallel GC (as mentioned earlier) uses multiple threads for garbage collection. Full GC, also known as a stop-the-world GC, pauses all application threads to perform a thorough sweep of the heap, collecting all unused objects. This can have significant performance impacts but is necessary at times.
