1.数组--->List

String[]  ss={"abc","def","xyz","aaaaaaaa","bbbb","abc"};

List<String> list=new ArrayList<String>(Arrays.asList(ss));//按添加顺序显示

System.out.println("list---->"+list);        //list---->[abc, def, xyz, aaaaaaaa, bbbb, abc]

2.数组--->Set

String[]  ss={"abc","def","xyz","aaaaaaaa","bbbb","abc"};

Set<String>set=new TreeSet<String>(Arrays.asList(ss));;//TreeSet有排序去重功能

System.out.println("set---->"+set);           //set---->[aaaaaaaa, abc, bbbb, def, xyz]
