1.数组--->List   

String[]  ss={"abc","def","xyz","aaaaaaaa","bbbb","abc"};  List
    
      list=new ArrayList
     
      (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
    
     set=new TreeSet
     
      (Arrays.asList(ss));;//TreeSet有排序去重功能System.out.println("set---->"+set);           //set---->[aaaaaaaa, abc, bbbb, def, xyz]
