生成带星期的日期格式

//例如输入:2017-11-29 16:30:00 则输出:2017-11-29 星期三 16:30
    public String getDate(String string_date){
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd EEE HH:mm");
        Date date=null;
        try {
            date = formatter.parse(string_date);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return sdf.format(date);
    }

       //此方法可以获取输入日期是星期几
       //ex:2017-11-29 ->星期三
       public static String getWeek(String sdate) {  
         Date date = strToDate(sdate);  
         Calendar c = Calendar.getInstance();  
         c.setTime(date);
         return new SimpleDateFormat("EEEE").format(c.getTime());  
     }  
      
     public static Date strToDate(String strDate) {  
         SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");  
         ParsePosition pos = new ParsePosition(0);  
         Date strtodate = formatter.parse(strDate, pos);  
         return strtodate;  
     }
