Not insert in database

Hi everyone. i'm a new one to this form.
I'm trying to insert values in emp table in oracle database but when using this code it accept values but not insert that in table. please help me on this. thanks in advance

the code is below

import java.io.*;
import java.sql.*;

public class JdbcTest3
{
	public static void main(String... args)
	{
		BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

Connection dbcon=null;
		Statement stmt=null;

try
		{
			Class.forName("oracle.jdbc.driver.OracleDriver");
			dbcon=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","scott","arun");	
			//stmt=dbcon.createStatement();
System.out.println("Connection Established.....");
			 stmt=dbcon.createStatement();
			System.out.println("Statement created.....");
			
			System.out.print("Employee ID : ");
			int employeeid=Integer.parseInt(br.readLine());
			System.out.print("First Name : ");
			String firstname=br.readLine();
			System.out.print("Last Name : ");
			String lastname=br.readLine();
			
			String query="insert into emp values ("+employeeid+",'"+firstname+"','"+lastname+"')";	
			int row=stmt.executeUpdate(query);

if(row!=0)
				System.out.println("Record Saved.");	
			else
				System.out.println("Record not Saved.");
		}
		catch(Exception e)
		{
			
		}
		finally
		{
			try
			{
				if(stmt!=null)	
					stmt.close();
				if(dbcon!=null)	
					dbcon.close();
			}
			catch(Exception e)
			{
				e.printStackTrace();
			}	
		}
	}
}

And the run of this program is

D:\My data\MCA\Sem 5\advance java codes\1506jdbccodes>java JdbcTest3
Connection Established.....
Statement created.....
Employee ID : 1
First Name : aa
Last Name : cc

Does Record Saved or Record Not Saved appear in output?

I think you need to call commit() on your Connection object, probably after the if-else block. Alternatively, setAutoCommit(true) after you have created it would suffice instead.

P.S. Never leave Exception handling blocks empty.

Arun,
welcome to java ranch.
As james said dont leave the catch block empty.
Keep e.printStackTrace() in your catch block.
And do let us know the error which you are facing.

James,
I think by default it will commit, if you keep connection.setAutocommit(false) explicitly then you need to do connection.commit() in your code.

Just checked Javadocs, you are right:

...By default a Connection object is in auto-commit mode, which means that it automatically commits changes after executing each statement...

Thanks to all. i got my mistake.

Arun, what was the solution?
