ArrayList from HashMap values

Is there a way to cast HashMap values to an ArrayList or do I have use the iterator? HashMap.values() returns a Collection and I thought i could cast it to an ArrayList but I get a ClassCastException.

 

是否有办法将HashMap转化为ArrayList?如果直接将HashMap.values() 强制转化为ArrayList 会报ClassCastException。

 

解决办法：

 

List myList = new ArrayList(myHashMap.values());
