import java.sql.*;

public class Jdbc{
	public static void Retrieve()throws Exception
	{
                 Connection con=setConnection();
	PreparedStatement p=con.prepareStatement("SELECT S_FARE FROM TR_AV WHERE S_TYPE=? AND TR_NO=?");
        p.setString(1,"AC FIRST CLASS");
        p.setInt(2, 1211);
        ResultSet r=p.executeQuery();
        r.next();
       String s=r.getString(1);
        System.out.print("String"+s);
	}
	public static void main(String[] args)throws Exception {

Are you serious? Are you getting an error? What is it you want us to look for?

One thing that's wrong is the following:

  ResultSet r=p.executeQuery();
String s=r.getString(1);   

There needs to be

r.next() 

in between.

It is still not working.it is throwing the following exception:
Exception in thread "main" java.sql.SQLException: Exhausted Resultset

1) have you read the API for the ResultSet next() method?
2) what do you think the error means?

The ResultsSet class behaviour for cursors and the use of the 'next' method is important but not too difficult a concept. It is however something you'll need to look up and understand.

There also needs to be an if statement in between.

Rather than saying you are still getting the error, it would be helpful to show the updated code.
