Android Unparseable date Exception

I get a Unparseable date when trying to parse a Date string that is sent to my android client.

This is the exception:

java.text.ParseException: Unparseable date: "2018-09-18T00:00:00Z" (at offset 19) at java.text.DateFormat.parse(DateFormat.java:571)

The date format my C# based backend sends (The C# object Property is DateTime):

2018-09-18T00:00:00Z

My Java Code where it fails:

SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss aa");
String targetDate = "2018-09-18T00:00:00Z";
Date date = dateFormat.parse(targetDate));

How can I change my code to parse the exact format sent by the backend?

The date format sent by your backend follows ISO-8601 instant format.

You can use LocalDate.parse(targetDate, DateTimeFormatter.ISO_INSTANT) to parse it.

You have to change the format String to:

SimpleDateFormat dateFormatParse = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss'Z'");
String targetDate = "2018-09-18T00:00:00Z";
Date dateString = dateFormatParse.parse(targetDate));
