find which type of garbage collector is running

Is there a way to tell what garbage collector is being used in a jvm by default?

Answer 1

This will print out a list of all of the Garbage Collectors currently loaded in your JVM.

import java.lang.management.*;
import java.util.List;

public class x {
    public static void main(String args[]) {
        List<GarbageCollectorMXBean> l = ManagementFactory.getGarbageCollectorMXBeans();
        for(GarbageCollectorMXBean b : l) {
            System.out.println(b.getName());
        }
    }
}
