设奥运5环为5个对象：A,B,C,D,E
则java程序如下：
ListInteger a=new ArrayListInteger(9);
ListInteger b=new ArrayListInteger();
ListInteger c=new ArrayListInteger();
ListInteger d=new ArrayListInteger();
ListInteger e=new ArrayListInteger();
ListInteger reslist =Arrays.asList(new Integer[] {1,2,3,4});
ListInteger res1list =Arrays.asList(new Integer[] {8,7,6,5});
b.add(reslist.get(0)).add(res1list.get(0));
c.add(reslist.get(1)).add(res1list.get(1));
d.add(reslist.get(2)).add(res1list.get(2));
e.add(reslist.get(3)).add(res1list.get(3));
