Garbage Collection by Java Coding. 

Sometimes for a large project, an exception named stack/memory overflow may generated, then we have to free the JVM(Java Virtual Machine) memory. here is the code.

import java.util.*;

public class GarbageCollection {

public static void main (String[] args) throws Exception {
Runtime rs = Runtime.getRuntime();
System.out.println("Free memory in Java Virtual Machine before Garbage Collection = "+rs.freeMemory());
rs.gc();
System.out.println("Free memory in Java Virtual Machine after Garbage Collection = "+rs.freeMemory());
}
