string[] to map

?

?

public static Map<Integer, Object> convertStringToMap(String[] value) {if (value == null) {return new HashMap<Integer, Object>();}Map<Integer, Object> ret = new HashMap<Integer, Object>();for (int i = 0; i < value.length; i++) {int key = getIntValue(value[i]);ret.put(key, key);}return ret;}

?

Map<Integer, Object> sendto = AppUtils.convertStringToMap(this.request.get().getParameterValues("sendto"));if(sendto.get(0)!=null){System.out.println("0");}if(sendto.get(1)!=null){System.out.println("1");}

?小问题还真容易忽略，如果你sendto.get("1")就不行了。
