Flex DateFormat validation in java
I have a XLSX file which contain 2 columns 1 being a formatted date, time or datetime field and other being the relavant format string of type FLEX. So this file contains Flex date format string with formatted value. This files can be contain more than one thousand such combination records. 
Eg:

 

> M/D/YYYY L:NN:SS A  --------- 7/4/1958 11:34:30 AM
> 
> 
>  MM/DD/YYYY  ------------------- 07/13/2009
> 
> 
>  L:NN:SS A  -----------------------             1:24:20 PM

What i need to know is, is there anyway that i can validate this given date , time or date time values at right side are formmated according to given FLEX format in the left side.
Important thing is , **this need to be happened in java side**.
