How to Resolve \'java.text.ParseException: Unparseable Date\' Exception?

Resolving "java.text.ParseException: Unparseable Date" Exception

When attempting to parse a date using SimpleDateFormat, an "Unparseable Date" exception may arise due to mismatched input string formats. To address this, the input string and SimpleDateFormat pattern must be aligned.

In this specific case, the input string "Sat Jun 01 12:53:10 IST 2013" does not correspond to the pattern "MMM d, yyyy HH:mm:ss" used by the SimpleDateFormat instance. To correctly parse the input, a different pattern is required.

The revised pattern below accommodates the specific elements in the input string:

SimpleDateFormat sdf = new SimpleDateFormat("EE MMM dd HH:mm:ss z yyyy", Locale.ENGLISH);

Additionally, to print the parsed date in the desired format, another SimpleDateFormat instance is required:

Date parsedDate = sdf.parse(date);
SimpleDateFormat print = new SimpleDateFormat("MMM d, yyyy HH:mm:ss");
System.out.println(print.format(parsedDate));

Notes:

• Including the appropriate locale in the SimpleDateFormat constructor ensures accurate date parsing, as day names can vary across different locales.
• Using the correct time zone name in the input string eliminates potential ambiguities and improves parse accuracy.
