欲构造ArrayList类的一个实例，此类实现了List接口

		List t = new List() {

			public int size() {
				// TODO Auto-generated method stub
				return 0;
			}

			public boolean isEmpty() {
				// TODO Auto-generated method stub
				return false;
			}

			public boolean contains(Object o) {
				// TODO Auto-generated method stub
				return false;
			}

			public Iterator iterator() {
				// TODO Auto-generated method stub
				return null;
			}

			public Object[] toArray() {
				// TODO Auto-generated method stub
				return null;
			}

			public Object[] toArray(Object[] a) {
				// TODO Auto-generated method stub
				return null;
			}

			public boolean add(Object e) {
				// TODO Auto-generated method stub
				return false;
			}

			public boolean remove(Object o) {
				// TODO Auto-generated method stub
				return false;
			}

			public boolean containsAll(Collection c) {
				// TODO Auto-generated method stub
				return false;
			}

			public boolean addAll(Collection c) {
				// TODO Auto-generated method stub
				return false;
			}

			public boolean addAll(int index, Collection c) {
				// TODO Auto-generated method stub
				return false;
			}

			public boolean removeAll(Collection c) {
				// TODO Auto-generated method stub
				return false;
			}

			public boolean retainAll(Collection c) {
				// TODO Auto-generated method stub
				return false;
			}

			public void clear() {
				// TODO Auto-generated method stub
				
			}

			public Object get(int index) {
				// TODO Auto-generated method stub
				return null;
			}

			public Object set(int index, Object element) {
				// TODO Auto-generated method stub
				return null;
			}

			public void add(int index, Object element) {
				// TODO Auto-generated method stub
				
			}

			public Object remove(int index) {
				// TODO Auto-generated method stub
				return null;
			}

			public int indexOf(Object o) {
				// TODO Auto-generated method stub
				return 0;
			}

			public int lastIndexOf(Object o) {
				// TODO Auto-generated method stub
				return 0;
			}

			public ListIterator listIterator() {
				// TODO Auto-generated method stub
				return null;
			}

			public ListIterator listIterator(int index) {
				// TODO Auto-generated method stub
				return null;

			public List subList(int fromIndex, int toIndex) {
