Parse date in french locale which can be found anywhere in the string

+1 vote
41 views

Example: consider this string
" Parse this date string 10 juil 2014 @@@parse date " OR "10 juil 2014" (This is easy with SimpleDateFormat using Locale.French) but I want the solution to extract date first from the string and then convert to Date using SimpleDateFormat.
