问题描述
我需要您帮助获得两个日期之间的字符串中的月份和年份列表。用户将以String格式输入两个日期:
I need your help in getting the list of months and the years in String between two dates. The user will enter two dates in the String format of:
String date1 ="JAN-2015";
String date2 ="APR-2015";
所以结果应该是:
- 2015年1月
- FEB-2015
- MAR-2015
我尝试使用以下代码,但它给了我错误的结果:
I tried using the following code but it gave me wrong results:
List<Date> dates = new ArrayList<Date>();
String str_date ="JAN-2015";
String end_date ="APR-2015";
DateFormat formatter ;
formatter = new SimpleDateFormat("MMM-yyyy");
Date startDate = formatter.parse(str_date);
Date endDate = formatter.parse(end_date);
long endTime =endDate.getTime() ;
long curTime = startDate.getTime();
while (curTime <= endTime) {
dates.add(new Date(curTime));
curTime ++;
}
for(int i=0;i<dates.size();i++){
Date lDate =(Date)dates.get(i);
String ds = formatter.format(lDate);
System.out.println(ds);
}
推荐答案
基本的java库,并得到你要求的结果。所以你可以修改date1和date2变量。
Using the less code possible and basic java libraries and getting the result you asked for. So you can modify the date1 and date2 variables.
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
public class Main {
public static void main(String[] args) {
String date1 = "JAN-2015";
String date2 = "APR-2015";
DateFormat formater = new SimpleDateFormat("MMM-yyyy");
Calendar beginCalendar = Calendar.getInstance();
Calendar finishCalendar = Calendar.getInstance();
try {
beginCalendar.setTime(formater.parse(date1));
finishCalendar.setTime(formater.parse(date2));
} catch (ParseException e) {
e.printStackTrace();
}
while (beginCalendar.before(finishCalendar)) {
// add one month to date per loop
String date = formater.format(beginCalendar.getTime()).toUpperCase();
System.out.println(date);
beginCalendar.add(Calendar.MONTH, 1);
}
}
}
