Validating date in java Hook up chatline
It also follows good thing from Joda library about keeping human and machine interpretation of date time separated.
They are also based on the ISO Calendar system and unlike their predecessor, class in class.
Java Beans Validation (Bean Validation) is a new validation model available as part of Java EE 6 platform.
All of us have come among situations when we have to parse user input for validation. First, it should have flagged the validation error, and second the date object obtained is completely useless. It is not intelligent by default to use the right characters for parsing and it uses what comes on its way (even slashes).
Other fields such as text or numeric are rather easy, but date date validation is little bit difficult and a small error can leave the application in unstable state. Solution: Use Simple Date Format’s set Lenient() method to bring the missing intelligence. Date; public class Test Set Lenient Output in console: //Wed Aug 12 GMT 184 //
since there is a calendar, there not only is no need for manual entry but it also avoids input error.. either to validate both the calendar date & manual entry (entered in dd/mm/yyyy) Or to prevent users from typing inside the date field (& use the calendar!
When I try to validate a date, it will either accept the manual date, or the calendar date but never both. ) (or prevent them from typing anything other than dd/mm/yyyy) ('ve tried regular expressions but it does not accept the value from the calendar) Thanks hopefully!
