It is the programmer's responsibility to ensure that objects no longer in use are no longer referenced by the application. That way the garbage collector can do its job and reclaim memory used by these objects. Try out the following code and check wether the GC guarentee that this application will not run out of memory public class Main { public static void main(String[] main) { List l = new LinkedList(); // Enter infinite loop which will add a String to the list: l on each iteration. do { l.add(new String("Hello, World")); } while(true); } } It is perfectly possible for a programmer to mistakingly create objects which never go out of scope, thus consuming more and more memory until all heap is exhausted.

public class Main {
public static void main(String[] main) {
List l = new LinkedList();
// Enter infinite loop which will add a String to the list: l on each iteration.
do {
l.add(new String(“Hello, World”));
} while(true);
}
