Java中List 去掉重复的值,并保持原先List顺序

代码如下:

 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     }
