有没有办法将Date对象格式化为Day和Month的固定长度,以便在列中保持良好的对齐? 例如:
15 May 2010 10 January 2010
而不是
15 May 2010 10 January 2010
谢谢!

查看java.util.Formatter类,其格式方法与String.format(...)相同,类似于System.out.printf。
例如:
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
public class FormatDateCalendar {
public static final String FORMAT_STRING = "%1$-3td %1$-9tB %1$tY";
public static void main(String[] args) {
Calendar c1 = new GregorianCalendar(2011, Calendar.FEBRUARY, 3);
Calendar c2 = new GregorianCalendar(2010, Calendar.MAY, 15);
Date today = new Date();
System.out.printf(FORMAT_STRING + "%n", c1);
System.out.printf(FORMAT_STRING + "%n", c2);
System.out.printf(FORMAT_STRING + "%n", today);
}
}
