How to Parse ISO-8601 DateTime with Colons in Offset Using Java?

Parsing ISO-8601 DateTime with Colons in Offset Using Java
When encountering a date and time string in the ISO-8601 format that includes a colon in the offset, parsing it in Java can prove challenging. Consider the specific case of a date and time string in the following format:
2013-04-03T17:04:39.9430000+03:00
To successfully parse this string and convert it to a more readable format, such as "dd.MM.yyyy HH:mm," we can utilize Java's SimpleDateFormat class.
The following Java code demonstrates how to parse and reformat the date and time string:
<code class="java">import java.text.SimpleDateFormat;
import java.util.Date;
public class Iso8601DateTimeParser {
public static void main(String[] args) {
// Input date string in ISO-8601 format
String dateString = "2013-04-03T17:04:39.9430000+03:00";
// Create SimpleDateFormat objects for input and output formats
SimpleDateFormat inFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
SimpleDateFormat outFormat = new SimpleDateFormat("dd.MM.yyyy HH:mm");
try {
// Parse the input date string into a Date object
Date dtIn = inFormat.parse(dateString);
// Reformat the Date object to the desired output format
String dtOut = outFormat.format(dtIn);
// Print the reformatted date string
System.out.println("Reformatted Date: " + dtOut);
} catch (ParseException e) {
// Handle parsing exception
System.err.println("Error parsing date string: " + e.getMessage());
}
}
}</code>This code snippet accomplishes the following steps:
- Creates two SimpleDateFormat objects, one for parsing the input date and time string and the other for formatting the output.
- Parses the input date and time string into a Date object.
- Reformats the Date object using the output format string.
- Outputs the reformatted date and time string.
