Validating date java

However, it’s a bit hard to validate the leap year , 30 or 31 days of a month, we may need basic logic as below. “31/11/2010” – November has 30 days only [Parser] Running: E:\workspace\mkyong\Date is valid : 1/1/2010 , true Date is valid : 01/01/2020 , true Date is valid : 31/1/2010 , true Date is valid : 31/01/2020 , true Date is valid : 29/2/2008 , true Date is valid : 29/02/2008 , true Date is valid : 28/2/2009 , true Date is valid : 28/02/2009 , true Date is valid : 31/3/2010 , true Date is valid : 31/03/2010 , true Date is valid : 30/4/2010 , true Date is valid : 30/04/2010 , true Date is valid : 31/5/2010 , true Date is valid : 31/05/2010 , true Date is valid : 30/6/2010 , true Date is valid : 30/06/2010 , true Date is valid : 31/7/2010 , true Date is valid : 31/07/2010 , true Date is valid : 31/8/2010 , true Date is valid : 31/08/2010 , true Date is valid : 30/9/2010 , true Date is valid : 30/09/2010 , true Date is valid : 31/10/2010 , true Date is valid : 31/10/2010 , true Date is valid : 30/11/2010 , true Date is valid : 30/11/2010 , true Date is valid : 31/12/2010 , true Date is valid : 31/12/2010 , true Date is valid : 32/1/2010 , false Date is valid : 32/01/2020 , false Date is valid : 1/13/2010 , false Date is valid : 01/01/1820 , false Date is valid : 29/2/2007 , false Date is valid : 29/02/2007 , false Date is valid : 30/2/2008 , false Date is valid : 31/02/2008 , false Date is valid : 29/a/2008 , false Date is valid : a/02/2008 , false Date is valid : 333/2/2008 , false Date is valid : 29/02/200a , false Date is valid : 31/4/2010 , false Date is valid : 31/04/2010 , false Date is valid : 31/6/2010 , false Date is valid : 31/06/2010 , false Date is valid : 31/9/2010 , false Date is valid : 31/09/2010 , false Date is valid : 31/11/2010 , false PASSED: Valid Date Test("1/1/2010") PASSED: Valid Date Test("01/01/2020") PASSED: Valid Date Test("31/1/2010") PASSED: Valid Date Test("31/01/2020") PASSED: Valid Date Test("29/2/2008") PASSED: Valid Date Test("29/02/2008") PASSED: Valid Date Test("28/2/2009") PASSED: Valid Date Test("28/02/2009") PASSED: Valid Date Test("31/3/2010") PASSED: Valid Date Test("31/03/2010") PASSED: Valid Date Test("30/4/2010") PASSED: Valid Date Test("30/04/2010") PASSED: Valid Date Test("31/5/2010") PASSED: Valid Date Test("31/05/2010") PASSED: Valid Date Test("30/6/2010") PASSED: Valid Date Test("30/06/2010") PASSED: Valid Date Test("31/7/2010") PASSED: Valid Date Test("31/07/2010") PASSED: Valid Date Test("31/8/2010") PASSED: Valid Date Test("31/08/2010") PASSED: Valid Date Test("30/9/2010") PASSED: Valid Date Test("30/09/2010") PASSED: Valid Date Test("31/10/2010") PASSED: Valid Date Test("31/10/2010") PASSED: Valid Date Test("30/11/2010") PASSED: Valid Date Test("30/11/2010") PASSED: Valid Date Test("31/12/2010") PASSED: Valid Date Test("31/12/2010") PASSED: In Valid Date Test("32/1/2010") PASSED: In Valid Date Test("32/01/2020") PASSED: In Valid Date Test("1/13/2010") PASSED: In Valid Date Test("01/01/1820") PASSED: In Valid Date Test("29/2/2007") PASSED: In Valid Date Test("29/02/2007") PASSED: In Valid Date Test("30/2/2008") PASSED: In Valid Date Test("31/02/2008") PASSED: In Valid Date Test("29/a/2008") PASSED: In Valid Date Test("a/02/2008") PASSED: In Valid Date Test("333/2/2008") PASSED: In Valid Date Test("29/02/200a") PASSED: In Valid Date Test("31/4/2010") PASSED: In Valid Date Test("31/04/2010") PASSED: In Valid Date Test("31/6/2010") PASSED: In Valid Date Test("31/06/2010") PASSED: In Valid Date Test("31/9/2010") PASSED: In Valid Date Test("31/09/2010") PASSED: In Valid Date Test("31/11/2010") =============================================== com.mkyong.regex.

When setting options via HTML attributes, remember to enable the validator by setting data-fv-date="true".You don't need to do that when using HTML 5 type="date" attribute (the format then will be forced to be YYYY-MM-DD).options can be either a date string in the format of YYYY-MM-DD or a Date object.We have also checked the leap year factor for the month of February.We have used "/" and "-" character as a separator within the date format but you are free to change that separator the way you want. “31/9/2010”, “31/09/2010” – September has 30 days only 10.

“31/6/2010”, “31/06/2010” -June has 30 days only 9.

The time field will allow input starting with 'hh:mm' following by an optional 'am' or 'pm'. The code behind the form is as follows: For each field in the form (first the dates, then the time field), a check is made as to whether the input is blank.

If not, the input is compared to the regular expression.

However I have no idea how to validate the date in my method class as i am fairly new to Java. the sort iof thing I've been taught to use is Date Formmater but not sure whether this is appropriate here?

if so wouldn't know how to use it Your question has attracted a lot of answers which recommend the Simple Date Format class. To give two examples, the parse() method cannot detect errornous months (i.e.

13th month) and the format for year can be burst with longer years.
