如何从列表中删除重复项而无需在Java中重新排序？

Question

I am trying to remove duplicates from my List object of the type String using Set Interface but the problem i face is that it also reorders my list which is something i don't want. I want to preserver the order of the list and remove duplicates only ?

static List<String>  StopNames = new ArrayList<String>();

StopNames.add(sCurrentLine);

Set<String> set = new HashSet<String>(StopNames);


for (String string : set) {

 System.out.println("Printing Set "+string);

}

只需为LinkedHashSet切换HashSet ，它会在删除重复项时保留插入顺序。
