Answer 1

如果您正在为您的特定情况寻找解决方案，它将是：

Date date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").parse("2012-05-20T09:00:00.000Z");
String formattedDate = new SimpleDateFormat("dd/MM/yyyy, Ka").format(date);

使用toSimpleDateFormat先到然后到parse() StringDateformat() DateString

Answer 3

package newpckg;

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

public class StrangeDate {

    public static void main(String[] args) {

        // string containing date in one format
        // String strDate = "2012-05-20T09:00:00.000Z";
        String strDate = "2012-05-20T09:00:00.000Z";

        try {
            // create SimpleDateFormat object with source string date format
            SimpleDateFormat sdfSource = new SimpleDateFormat(
                    "yyyy-MM-dd'T'hh:mm:ss'.000Z'");

            // parse the string into Date object
            Date date = sdfSource.parse(strDate);

            // create SimpleDateFormat object with desired date format
            SimpleDateFormat sdfDestination = new SimpleDateFormat(
                    "dd/MM/yyyy, ha");

            // parse the date into another format
            strDate = sdfDestination.format(date);

            System.out
                    .println("Date is converted from yyyy-MM-dd'T'hh:mm:ss'.000Z' format to dd/MM/yyyy, ha");
            System.out.println("Converted date is : " + strDate.toLowerCase());

        } catch (ParseException pe) {
            System.out.println("Parse Exception : " + pe);
        }
    }
}
