Java ParseException while attempting String to Date parsing

Question

I\'m having a hard time Parsing/Formatting a Date string received back from a web service. I\'ve attempted multiple approaches, but with no luck.

Sample Dat

Answer 1

SimpleDateFormat isoDateFormat = new SimpleDateFormat("yyyy-mm-dd'T'hh:mm:ss'Z'");
SimpleDateFormat viewFriendlyDateFormat = new SimpleDateFormat("dd/MMM/yyyy hh:mm:ss aaa");
String viewFriendlyDate = "";
try { 
    Date date = isoDateFormat.parse(timestamp);
    viewFriendlyDate = viewFriendlyDateFormat.format(date);

} catch (ParseException e) { 
    e.printStackTrace(); 
} 

Answer 2

You could try:

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
String dateString = dateString.replace("Z", "GMT+00:00");
Date date = dateFormat.parse(dateString);

The above code should correctly handle the case where a timezone is specified in the date. As Z represents the UTC/GMT timezone it is replaced by GMT so the SimpleDateFormat can interpret it correctly (i would love to know a cleaner way of handling this bit if anyone knows one).

Answer 3

Try,

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");

Answer 4

This worked for me

    SimpleDateFormat isoDateFormat = new SimpleDateFormat("yyyy-mm-dd'T'hh:mm:ss'Z'");
    SimpleDateFormat viewFriendlyDateFormat = new SimpleDateFormat("dd/MMM/yyyy hh:mm:ss aaa");
    String viewFriendlyDate = "";
    try {
        Date date = isoDateFormat.parse(timestamp);
        viewFriendlyDate = viewFriendlyDateFormat.format(date);

    } catch (ParseException e) {
        e.printStackTrace();
    }

Answer 5

This pattern should parse the date you provide: "yyyy-MM-dd'T'HH:mm:ss'Z'".
If you want to use SimpleDateFormat and you have a limited number of variations, you can create separate formatters for each pattern and chain them:

Date date = formatter1.parse(info.AiringTime);
if (date == null)
{
  date = formatter2.parse(info.AiringTime);
  if (date == null)
  {
    date = formatter2.parse(info.AiringTime);
    if (date == null)
    {
      date = formatter3.parse(info.AiringTime);
    }
  }
}

or put them in a list and iterate until non-null or no more formatters.
If you have too many patterns for this to be practical, you can parse it yourself or try one of these libraries.
