在1.5里面容器要事先指定類型如:
List<Integer> lt=new LinkedList<Integer>();
lt.add(new Integer(0));
如果這樣定義
List lt=new LinkedList();
lt.add(new Integer(0));
就會報note了
Note: D:\1_jb\JavaApplication1\src\javaapplication1\Main.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
這樣
??????? ArrayList<HashMap> fieldGetList=new ArrayList<HashMap>();
??????? HashMap<String,String> annal=new HashMap<String,String>();
??????? annal.put("111","222");
??????? fieldGetList.add(annal);
就可以編譯OK了
