Basically HTML5 can be used to develop 3D applications.

In this example, the date fields will only accept input that matches the pattern 'dd/mm/yyyy' (this could just as easily be changed to 'yyyy-mm-dd' or 'mm/dd/yyyy').Rather regular expressions work character by character. [1-9]› to match 3 followed by 0 or 1, or to match 1 or 2 followed by any digit, or to match an optional 0 followed by 1 to 9. [0-9]$"; Pattern pattern = Pattern.compile(regex); for(String date : dates) Output: 1/1/11 : true 01/01/11 : true 01/01/2011 : true 01/1/2011 : true 1/11/2011 : true 1/11/11 : true 11/1/11 : true List dates = new Array List(); //With leading zeros dates.add("01/01/11"); dates.add("01/01/2011"); //Missing leading zeros dates.add("1/1/11"); dates.add("01/1/2011"); dates.add("1/11/2011"); dates.add("1/11/11"); dates.add("11/1/11"); String regex = "^[0-3][0-9]/[0-3][0-9]/(? Because of this, you have to choose how simple or how accurate you want your regular expression to be. This is the simplest way to validate a dd/MM/yyyy date format string.

And it does work brilliantly except the fact that it cannot validate for months which have less than 31 days for example 30/02/2014 will be considered as a valid date. Now you can ask questions directly to me on my new site ASPForums.
