Question

Hello,
I don't know what it doesn't work with this code. It's about create and update oracle tables throw Java.
can someone just check the code and tell me where is the problem ?
thanks in advance
import java.sql.*;
public class SQL_QUERIES_TESTING {
     public static void main(String[] args) {
          Statement stmt=null;
          ResultSet rs=null;
          Connection con=null;
               try {     
               String url="jdbc:oracle:thin:@SS-EC55E45BC763:1521:faiz";
               String driver="oracle.jdbc.driver.OracleDriver";
               String user="HR";
               String pwd="HR";
               Class.forName(driver);
               con=DriverManager.getConnection(url,user,pwd);
               String CreateCoffeeTable="CREATE TABLE COFFEE"+"(COFFEE_TYPE VARCHAR(32), DEALER_ID INTEGER, PRICE FLOAT,"+"SALES INTEGER, TOTAL INTEGER)";
               stmt=con.createStatement();
               stmt.executeUpdate(CreateCoffeeTable);
               stmt.executeUpdate("INSERT INTO COFFEE" + "VALUES ('French_Roast', 49, 8.99, 0, 0)");
               rs.close();
               stmt.close();
               con.close();
               rs.close();
               stmt.close();
               con.close();
          } catch (ClassNotFoundException e) {
               try {
                    stmt.close();
                    con.close();
               } catch (SQLException e1) {
                    e1.printStackTrace();
               e.printStackTrace();
          } catch (SQLException e) {
               try {
                    System.out.println("Execption :"+e.getMessage());
                    stmt.close();
                    con.close();

}

If it's not doing what you expect it to do, then you do know what's not working, right? How about letting us in on the secret? It would help us help you.
can someone just check the code and tell me where is the problem ?Remember, no one's sitting idle. If you really want help, you'll have to post the stack trace and exceptions that you're getting and an explanation of what you need to do and what's actually happening. If you ever, really need your code to be run, it'll have to be complete and should take minimum effort on the part of someone helping you out to run. Usually not a way out with JDBC since there'll be DBs involved.
So make an effort, track down the exceptions and the lines which cause them. Post the stack trace. Give a description of your problem.
People on the forum help others voluntarily, it's not their job.
Help them help you.
