ArrayList list = new ArrayList();
TreeMap tm = Calculate.tjj(0);
// 倒序
NavigableSet descendingKeySet = tm.descendingKeySet();
// 顺序
// Set testset = tm.keySet();
Iterator it = descendingKeySet.iterator();
while (it.hasNext()) {

int key = it.next();
System.out.println("key:" + key);
int paramObject = tm.get(key);
System.out.println(paramObject);
list.add(paramObject);
