关于java 循环创建 Map<String, Object>的问题
Map<String, Object> map1 = new HashMap<String, Object>();
map1.put("url", car_real_info[3]);
map1.put("car_where", car_real_info[2]);
map1.put("car_String", car_real_info[0]);
map1.put("car_number", car_real_info[1]);
Map<String, Object> map2 = new HashMap<String, Object>();
map2.put("url",car_real_info[8]);
map2.put("car_where",car_real_info[7]);
map2.put("car_String",car_real_info[5]);
map2.put("car_number",car_real_info[6]);
Map<String, Object> map3 = new HashMap<String, Object>();
map3.put("url",car_real_info[13]);
map3.put("car_where",car_real_info[12]);
map3.put("car_String",car_real_info[10]);
map3.put("car_number",car_real_info[11]);
Map<String, Object> map4 = new HashMap<String, Object>();
map4.put("url",car_real_info[18]);
map4.put("car_where",car_real_info[17]);
map4.put("car_String",car_real_info[15]);
map4.put("car_number",car_real_info[16]);
data.add(map1);
data.add(map2);
data.add(map3);
data.add(map4);
}

Map<String, Map<String, Object>> map=new HashMap<String, Map<String, Object>>();
for (int i = 0; i < 3; i++) {
Map<String, Object> mapchild=new HashMap<String, Object>();
mapchild.put("url", 1);
mapchild.put("car_where", 2);
mapchild.put("car_String", 3);
mapchild.put("car_number", 4);
map.put("map"+i, mapchild);
}
for (int i = 0; i < map.size(); i++) {
//这里面data.add(map.get("map"+i));
System.out.println(map.get("map"+i).get("url"));
}
