You need to use DateFormat class's parse method for this.
DateFormat df=DateFormat.getDateInstance();
myDate = df.parse(above date string);

If you get parse exception in the above code, then the date is not in the proper format.

Check this for more details:

     public static boolean validDate( String date, String format )
      {
          try
          {
              SimpleDateFormat sdf = new SimpleDateFormat( format ) ;
              sdf.setLenient( false ) ;
              sdf.parse( date ) ;
              return true ;
          } catch (Exception e)
          {
              return false ;
          }
      }

public static void main(String[] args) {
      if ( validDate( "02/02/2006", "MM/dd/yyyy" ) )
      {
         System.out.println("valid");
      }

}
