Parseerror bei richtiger Syntax

[Templarthelast]

In meinem Programm rufe ich emails von einem mailServer hab und durchsuche dabei ihren Header nachdem Datum, an dem sie empfangen werden. Dabei erhalte ich

Received: (qmail invoked by alias); 26 Mar 2012 00:17:10 -0000

als Rückgabe und mit

emailRec = recvreply.substring(36, 56)

dann einen String raus, alldings gibt mir der Compiler bei

SimpleDateFormat stringToDate = new SimpleDateFormat("dd MMM yyyy hh:mm:ss");
emailDate = stringToDate.parse(emailRec)

den Fehler aus:

java.text.ParseException: Unparseable date: "26 Mar 2012 00:17:10"

dd MMM yyyy hh:mm:ss

Das kleine h steht für

Hour in am/pm (1-12)

. Da gibts dann keine nullte Stunde. Verwende stattdessen K.

 

[SlaterB]

der Fehler ist aber ein anderer, und ich möchte auch anmerken dass die 430 Zeilen Code doch relativ nutzlos sind, wenn schon zwei entscheidende Zeilen identifiziert

zum Fehler bei SimpleDateFormat bietet sich immer und immer wieder an, den umgekehrten Weg zu gehen:
was kommt raus wenn man ein Date zu String parst und kann dieser Text dann gelesen werden?

public class Test
{
    public static void main(String[] args) throws Exception
    {
        Date date = new Date(112, 2, 26, 0, 17, 10);
        SimpleDateFormat stringToDate = new SimpleDateFormat("dd MMM yyyy hh:mm:ss");
        System.out.println(stringToDate.format(date));
        
        String st = "26 Mrz 2012 12:17:10";
        System.out.println(stringToDate.parse(st));
        
    }
}

die Lösung habe ich dann quasi schon mitgepostet: deutsche Locale, wahrscheinlich auf Englisch umzustellen

 

[Templarthelast]

Ich hab es mal mit

dd MMM yyyy HH:mm:ss

und

dd MMM yyyy kk:mm:ss

versucht aber das Problem bleibt.

 

[nillehammer]

Wahrscheinlich ist die Locale das Problem.

new SimpleDateFormat("dd MMM yyyy hh:mm:ss");

Erzeugt ein SimpleDateFormat mit der Default-Locale des Systems. Die ist bei Dir wahrscheinlich "de". Wenn Du jetzt das englische Datum Deiner Mail mit deuscher Locale parst, kommt er mit der Abkürzung für den Monat "Mar" nicht zurecht (im Deutschen ist die dreibuchstabige Abkürzung des Monats März nämlich "Mrz"). Nutze folgenden Konstruktor, um das zu lösen:

new SimpleDateFormat("dd MMM yyyy hh:mm:ss", Locale.US);

[EDIT]
SlaterB hat's ja auch schon geschrieben...

Danke mit funktioniert es, aber auf solche Sachen muss man erstmal kommen..
