Error by converting date: Unparseable date in JAVA

I can't find the problem. I'm trying to convert the date:

"Thu, 10 Jul 2014 13:33:26 +0200"

from string to Date with this code:

String formatType = "EEE, dd MMM yyyy HH:mm:ss Z";
Date startzeit = new SimpleDateFormat(formatType).parse(einsatz.getString("startzeit"));

but I'm getting this exceptoin:

java.text.ParseException: Unparseable date: "Thu, 10 Jul 2014 13:33:26 +0200"

java.time

In March 2014, Java 8 introduced the modern, java.time date-time API which supplanted the error-prone legacy java.util date-time API. Any new code should use the java.time API.

Solution using modern date-time API

You can parse your date-time string to an OffsetDateTime using the inbuilt DateTimeFormatter#RFC_1123_DATE_TIME.

Demo:

class Main {
    public static void main(String args[]) {
        OffsetDateTime odt = OffsetDateTime.parse("Thu, 10 Jul 2014 13:33:26 +0200",
                DateTimeFormatter.RFC_1123_DATE_TIME);
        System.out.println(odt);
    }
}

Output:

2014-07-10T13:33:26+02:00

Online Demo

Note: If for some reason, you need an instance of java.util.Date, let java.time API do the heavy lifting of parsing your date-time string and convert odt from the above code into a java.util.Date instance using Date date = Date.from(odt.toInstant()).

You're creating a SimpleDateFormat without specifying a locale, so it'll use the default locale. By the looks of your variable names, that may not be English - so it'll have a hard time parsing "Thu" and "Jul".

Try:

String formatType = "EEE, dd MMM yyyy HH:mm:ss Z";
Date startzeit = new SimpleDateFormat(formatType, Locale.US)
                        .parse(einsatz.getString("startzeit");

(That works for me, with your sample value.)
