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"); 
}};
