[FONT=Georgia][SIZE=3][COLOR=DarkGreen]
hi to all
here is my doubt
my program is to do like this
1.in the program there is a start date and end date, when we select the two dates it has to go to the database.
2.in database there is a table called holidays,entered star and end dates has to go there and to verify that the dates are in there, if the dates are available means it has to tel that particular day is holiday r sunday r satuday.
for example:
if i am entering 5days(1,2,3,4,5)
it has to go to database and to see whether these days are in saturday, sunday, r any public holiday.
if it is in holiday means it has to tel that 1,4,5 is not in holidays
remaining 2,3 are holidays
here is the java code
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.text.*;
import java.sql.*;
public class compareDates
public static boolean compareDates(String dDateA, String dDateB)
             System.out.println("Entered into Compare Dates");
             SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
             ParsePosition pos = new ParsePosition(0);
             ParsePosition pos1 = new ParsePosition(0);
            Date startDate = formatter.parse(dDateA, pos);
            Date endDate = formatter.parse(dDateB, pos1);
          // Compare the Dates
            boolean flag = false;
            System.out.println("Start Date :"+startDate);
            System.out.println("End Date   :"+endDate);
            if(startDate.before(endDate))
                 flag = true;
           System.out.println("Compare Flag :"+flag);
            return flag;
    public static void main(String args[])
  Connection con = null;
               try
        String driverName = "com.mysql.jdbc.Driver"; // MySQL MM JDBC driver
          Class.forName (driverName);
          // Create a connection to the database
          String serverName = "192.168.10.5";
          String mydatabase = "Trainees";
          String url = "jdbc:mysql://" + serverName +  "/" + mydatabase; // a JDBC url
          String username = "josep";
          String password = "josep";
          con = DriverManager.getConnection(url, username, password);
          System.out.println("Connected");
  Statement stmt = null;
          ResultSet rset      = null;
          stmt = con.createStatement();
          rset = stmt.executeQuery ("SELECT * FROM Holiday");
  catch(Exception e)
     System.err.println("Exception: " + e.getMessage());
finally
       try
         if(con != null)
           con.close();
catch(SQLException e) {}
   try
    BufferedReader br=new BufferedReader(new InputStreamReader( System.in));
    System.out.println ("Enter Start Date (dd/mm/yyyy)");
    String dDateA=br.readLine();
    System.out.println("Enter End Date (dd/mm/yyyy)");
    String dDateB= br.readLine();
    compareDates cd= new compareDates();
    boolean before = cd.compareDates(dDateA,dDateB);
    if(!before)
     System.out.println("Please enter the Correct Date ");
   catch(Exception e)
              System.out.println("Exception in main Class :"+e.getMessage());

Answer 1

I'm a little confused about your requirements, but I'm going to attempt to answer the question that I think you're asking. Basically, Date1, Date2, Date3, Date4, and Date5 are consecutive days in a calendar. You have a table called Holiday which holds holidays and weekends as dates. You want to know if any of your dates are in the Holiday table.
You can
1. Write a query to ask for all Holidays between Date1 and Date5. Compare the results to your entry set using iteration, and print out the differences.
2. Iteratively query whether Date1 is in Holiday, and if it is add it to your own holidayList. If it isn't, add it to your own nonHolidayList.
Approach 1 will be better for performance, but I can't tell if this is a professional application. If it is, you need to consider writing a persistence layer to interact with the database.
