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]
