用Java显示每月的两位数字
使用“d”日期转换字符来显示两位数字的月份，例如27、28、20等。
System.out.printf("Two-digit day of the month: %td\n",d);上面的d是一个日期对象-
Date d = new Date();
以下是一个例子-
示例
import java.util.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
public class Demo {
public static void main(String[] args) throws Exception {
Date d = new Date();
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a");
String format = dateFormat.format(d);
System.out.println("Current date and time = " + format);
System.out.printf("Four-digit Year = %TY\n",d);
System.out.printf("Two-digit Year = %ty\n",d);
System.out.printf("Three-digit Day of the Year: %tj\n", d);
System.out.printf("Two-digit month: %tm\n",d);
System.out.printf("Two-digit day of the month: %td\n",d);
}
}输出结果
Current date and time = 26/11/2018 12:20:33 PM Four-digit Year = 2018 Two-digit Year = 18 Three-digit Day of the Year: 330 Two-digit month: 11 Two-digit day of the month: 26
