Filtering without Lambda or Java 8

I wanted a way to filter generally without using Lambda or Java 8.

	public class CollectionsUtils {
	public static void remove(List<?> items, Filter<Object> filter) {
	Iterator<?> iterator = items.iterator();
	while (iterator.hasNext()) {
	if (filter.shouldRemove(iterator.next())) {
	iterator.remove();
	}
	}
	}
	}

	public interface Filter<T> {
	public boolean shouldRemove(T t);
	}

	List<Map.Entry<String, Object>> list = new ArrayList<Map.Entry<String, Object>>(entries);
	//remove negative values
	CollectionsUtils.remove(list, new Filter<Object>() {
	public boolean shouldRemove(Object o1) {
	Map.Entry<String, Object> entry = (Map.Entry<String, Object>)o1;
	Double d1 = Double.parseDouble(entry.getValue().toString());
	return d1<0.25;
	}
	});
