Hi Manoj,

There is no direct function to do that.
You can do something like this.: 
string s='20170320';
string year=s.substring(0,4);
string month=s.substring(4,6);
string day=s.substring(6);
system.debug(day+' '+month+' '+year);
Date tempDate = Date.newInstance(integer.valueof(year), integer.valueof(month), integer.valueof(day));
string FinalDate=tempDate.format();
system.debug(FinalDate);

Let me know if it helps
Thanks!

Hi Manoj,

In the controller, you can use text functions to split the text into the year, month and day and use the date function to convert the text to the date value. 
Date myDate = Date.newInstance(2017, 03, 20);
If you would like to know more, follow the links below
Date functions: link (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_methods_system_date.htm).
Sting functions: link (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_methods_system_string.htm)

Hope it helps

Hi Manoj,
Put all these values in a list of string type and then start a for loop to traverse that list and write date extraction logic inside that for loop and add the final dates to a new list of string type.
