如题所述

Answer 1

public static void main(String[] args) {
Map<String,Object> map = new HashMap<String,Object>();
Map<String,String> mapNew = new HashMap<String,String>();
map.put("1", 11);
map.put("2", 11);
map.put("3", 11);
map.put("4", 11);
for (String string : map.keySet()) {
mapNew.put(string, map.get(string).toString());
}
System.out.println(mapNew.toString());

}
你说的是泛型的Object转换成String吗？这是代码，希望能帮到你！本回答被提问者采纳
