[b]Java JDBC and Oracle DB URGENT HELP PLEASE[/b]

Question

Hello, I am a newbie. I'm very interested in Java in relation to JDBC, Oracle and SAP.I am trying to connect to an Oracle DB and I have problems to display the output on the consule in my application. What am I doing wrong here . Please help me. This is my code: Please Explain
import java.sql.*;
import java.sql.DriverManager;
import java.sql.Connection;
public class SqlConnection {
public static void main(String[] args) {
Class.forName("oracle.jdbc.driver.OracleDriver"); //Loading the Oracle Driver.
Connection con = DriverManager.getConnection
("jdbc:orcle:thin:@34.218.5.3:1521:ruka","data","data"); //making the connection.
Statement stmt = con.createStatement ();// Sending a query to the database
ResultSet rs = stmt.executeQuery("SELECT man,jean,test,kok FROM sa_kostl");
while (rs.next()) {
String man = rs.getString("1");
String jean = rs.getString("2");
String test = rs.getString("3");
String kok = rs.getString("4");
System.out.println( man, jean, test,kok );//here where my the
//compiler gives me errors
stmt.close();
con.close();
}

Hello, I am a newbie. I'm very interested in Java in
relation to JDBC, Oracle and SAP.I am trying to
connect to an Oracle DB and I have problems to
display the output on the consule in my application.
What am I doing wrong here . Please help me. This is
my code: Please Explain
import java.sql.*;
import java.sql.DriverManager; <--- Why do you have these (java.sql.* is enough)
import java.sql.Connection;
public class SqlConnection {
public static void main(String[] args) {// Where's the try/catch block?
>
Class.forName("oracle.jdbc.driver.OracleDriver");
//Loading the Oracle Driver.
Connection con = DriverManager.getConnection
("jdbc:orcle:thin:@34.218.5.3:1521:ruka","data","data"
); //making the connection.
Statement stmt = con.createStatement ();// Sending a
query to the database
ResultSet rs = stmt.executeQuery("SELECT
man,jean,test,kok FROM sa_kostl");
while (rs.next()) {
String man = rs.getString("1");
String jean = rs.getString("2");
String test = rs.getString("3");
String kok = rs.getString("4");
System.out.println( man, jean, test,kok );//here
where my the
//compiler gives me errors
stmt.close();
con.close();
}The compiler is probably complaining about the lack of a try/catch block.
The fact that you can't understand the compiler messages, and didn't read the javadocs enough to know that you needed a try/catch block, suggest to me that you need to learn a lot more about Java. This is pretty fundamental stuff.
When you have problems, it's best to include information about what the compiler or runtime is telling. Error messages and stack traces are helpful.
In your case the error is so elementary that more information isn't necessary.
