how to make different date format validation ?

hi, have a nice day, i try to create some validation for date with different date format , for example, i may have DD/mm/yyyy , mm/dd/yyy , and yyyy-mm-dd ,

when i get some dates string like different date format, how to i compare it with other , and get know of which one is larger ?

thank you very much for guidance

how would you know if

13/01/2005 and 01/13/2005 is correct?

or if

01/02/2006 is January 2nd or Feb. 1st?

the date string actually get from date-picker(calendar), and i set parameter of date format from property file, date format in property eventually get though from java code(jsp) and set the dateformat for calendar using scriptlet

for example , if property file set field like dateformat="MM/dd/yyyy" , then the date-picker(calendar) will display in this defined format and also the return value would be following the defined format as well

look at this example here that I posted a prototype, with a slight change, you can make it work for your code.
