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"); 
}};
