日期格式问题字符串到java util日期

Question

I am new to Date functions. i have a date as a string '03/10/2014' - month/date/year. i need to convert this like '10-MAR-14' util date format. How can i do this please help me.

i used 'MM/dd/yyy' and 'dd-MMM-yyy' formats.

    public static Date convertStringToDate(String aMask, String strDate)
            throws ParseException {
SimpleDateFormat df;
            Date date;
            df = new SimpleDateFormat(aMask);

            if (log.isDebugEnabled()) {
                log.debug("converting '" + strDate + "' to date with mask '" + aMask + "'");
            }

            try {
                date = df.parse(strDate);
            } catch (ParseException pe) {
                //log.error("ParseException: " + pe);
                throw new ParseException(pe.getMessage(), pe.getErrorOffset());
            }

            return (date);

to do this. but gives me parse exception. Appreciate your help

but database column has the date-Month-year eg: 09-MAR-14. this does not give the result. i need to this conversion for hibernate criteria search. Database has results. but this conversion does not give the results.

你错过了表达式中的y ，使用MM/dd/yyyy

The following code will make a method and use it your logic

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



public class ex {
     public static void main(String[] args) {
    // TODO Auto-generated method stub

    SimpleDateFormat sdf1 = new SimpleDateFormat("dd-M-yyyy");
    String dateInString = "15-08-2014";
    Date date = null;
    try {
        date = sdf1.parse(dateInString);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yy");   

    Calendar calendar = new GregorianCalendar(date.getYear(),date.getMonth(),date.getDate());   
    System.out.println("Date :" + sdf.format(calendar.getTime()));
}

} `

It seems that the MSDN library has a format utility that can be downloaded to your project. See the link
