LinkedListMultimap用法

public static void main(String[] args) {
		LinkedListMultimap groupdMap = LinkedListMultimap
				.create();
		for (int i = 0; i < 100; i++) {
			groupdMap.put(i % 10, "value_" + i);
		}
		System.out.println("" + groupdMap.size());
		System.out.println("" + groupdMap.keys().size());
		System.out.println("" + groupdMap.keySet().size());
		System.out.println("" + groupdMap.get(0));
		Iterator> it = groupdMap.entries().iterator();
		int count = 0;
		while (it.hasNext()) {
			it.next();
			System.out.println(count);
			count++;
		}
	}

Iterator>> it2 = groupdMap.asMap()
