java List＜HashMap＜String,Object＞＞ 遍歷修改

List<HashMap<String,Object>> DataSource;
int i=0;
for (Map<String, Object> item : DataSource) {
for (String k : item.keySet()) {
if (k.equals("input_date")) { //此句為判斷條件可去掉
Object b = item.get(k);
String data=b.toString();
boolean status = data.contains(".0"); //如果包含 .0 用空串替換
if (status) {
String stopTime=data.replace(".0","");
((Map)DataSource.get(i)).put( k ,stopTime);
}
}
}
i++;
}
