java中快速创建带初始值的List和Map实例

List<String> sList = new ArrayList<String>(); sList.add("str1"); sList.add("str2"); 

Map<String,String> sMap = new HashMap<String, String>(); sMap.put("k1", "v1"); sMap.put("k2", "v2"); 

List<String> sList = Arrays.asList("str1", "str2");//这种方法生成的list，是不支持添加或删除元素的

private Map<Integer, String> newsEventMap = new HashMap<Integer, String>(){{ put("k1","v1"); put("k2","v2"); }};
