Java中List 去掉重复的值，并保持原先List顺序

 1    

 2     private List<YourBean> removeDuplicate(List<YourBean> list) {

 3         Set<YourBean> set = new HashSet<YourBean>();

 4         List<YourBean> newList = new ArrayList<YourBean>();

 5         for (Iterator<YourBean> iter = list.iterator(); iter.hasNext();) {

 6             YourBean element = (YourBean) iter.next();

 7             if (set.add(element))

 8                 newList.add(element);

 9         }

10         return newList;

11     }
