Answer / anjum rehbar khan
Yes we can send arequest to garbage collection by writing a
simple line of code:
System.gc();
OR
Runtime.gc();
But it is simply a request not a order to JVM
because Garbage collection is JVM dependent

Answer / uv
As far as I know,it is not required to call the garbage
collector.
It automatically and periodically removes the unused
objects by an algorithm known as "Mark and Sweep".
However, if we intentionally want to call it then the above
suggestions are perfect.
Anyone who feels that it is incorrect, please feel free to
correct me.

Answer / ashwani maddeshiya
static void gc() // Requests GC to run
static void runFinalization() // Requests finalizers to run
OR
mport java.util.*;
class GarbageCollectionDemo
{
public static void main(String s[]) throws Exception
{
// Get runtime environment
Runtime rt = Runtime.getRuntime();
System.out.println("Free memory before Garbage Collection = "+rt.freeMemory());
// Apply garbage collection
rt.gc();
System.out.println("Free memory after Garbage Collection = "+rt.freeMemory());
}
}
