java - Joda Time - 月份的日期和年份的月份不返回 2 位数字输出

Question

我有以下代码:

String dateUTC = "2013-09-08T10:23:54.663-04:00";
org.joda.time.DateTime dateTime = new DateTime(dateUTC);
System.out.println(" Year : " + dateTime.getYear());
System.out.println(" Month : " + dateTime.getMonthOfYear());
System.out.println(" Day : " + dateTime.getDayOfMonth()); 

The Output of this program is :
Year : 2013
Month : 9 // I want this to be 2 digit if the month is between 1 to 9
Day : 8 // I want this to be 2 digit if the month is between 1 to 9

有什么方法可以使用 Joda API 以 2 位数字检索月份和年份的值。

Answer 1

您可以简单地使用 AbstractDateTime#toString(String)

System.out.println(" Month : "+ dateTime.toString("MM"));
System.out.println(" Day : "+ dateTime.toString("dd"));
