Here is the code of program:

public class DateToLong {

  public static void main(String[] args) {

    try {

      String str_date="11-June-07";

      DateFormat formatter ; 

      Date date ; 

      formatter = new SimpleDateFormat("dd-MMM-yy");

      date = (Date)formatter.parse(str_date); 

      long longDate=date.getTime();

      System.out.println("Today is " +longDate );

    }

    catch (ParseException e){

      System.out.println("Exception :"+e);   

    }
