Java中如何获取日期对应的星期？

方法一、
public static String getFullDateWeekTime(String sDate){
  try{
   String formater = "yyyy-MM-dd HH:mm:ss";
   SimpleDateFormat format = new SimpleDateFormat(formater);
   Date date=format.parse(sDate);
   format.applyPattern("yyyy-MM-dd E HH:mm:ss");
   return format.format(date);
  }catch(Exception ex){
   System.out.println("TimeUtil  getFullDateWeekTime"+ex.getMessage());
   return "";
  }
 }

[@more@]方法二、

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class Test {
public static void main(String[] args) {
 final String dayNames[] = { "星期日", "星期一", "星期二", "星期三", "星期四", "星期五",
   "星期六" };

String s = "2006-01-12 16:30";
 SimpleDateFormat sdfInput = new SimpleDateFormat("yyyy-MM-dd HH:mm");

Calendar calendar = Calendar.getInstance();
 Date date = new Date();

try {
  date = sdfInput.parse(s);
 } catch (ParseException e) {
  e.printStackTrace();
 }

calendar.setTime(date);
 int dayOfWeek = calendar.get(Calendar.DAY_OF_WEEK)-1;
 if(dayOfWeek<0)dayOfWeek=0;
System.out.println(dayNames[dayOfWeek]);
}
}
