Question

Trying this in the title environment:

http://www.javadb.com/check-if-a-string-is-a-valid-date

However, it isn’t working in the right way. When dateFormat.parse(inDate.trim()); is called, it doesn’t throws an error, instead it makes a plus one to the date.

For example, if inDate.trim() is "2005-02-29", then it makes the parsing like "2005-03-01".

Obviously, I won’t this behavior. What can be done?

Answer 1

Set the setLenient() method on the SimpleDateFormat to false to throw errors in such cases:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
sdf.setLenient(false);
System.out.println(sdf.parse("2005-02-29")); // This would throw parse exception.
