Java中定义Map恒量，List常量

public final static Map map = new HashMap();    static {        map.put("key1", "value1");        map.put("key2", "value2");    } 

public final static Map<String, Fragment> NAV_ITEM_ADPTER = new HashMap<String, Fragment>() {      {          put("拍录传", new CameraFragment());          put("集群对讲", new GroupTalkFragment());          put("视通", new VideoCallFragment());          put("位置", new PositionFragment());          put("浏览", new BrowseFragment());          put("消息", new MsgFragment());          put("群组", new GroupFragment());          put("设置", null);          put("退出", null);      }  };  

public final static List<String> LIST = Arrays.asList("one","two","three");
