New to Java

Hi, I'm writing a program that pulls all data from the database with a simple "SELECT * FROM [TABLE NAME]. The problem is that I don't know how to set it up properly. My code will only connect to the database but not execute the query. Please help.



{code}import java.sql.*;
import java.util.Properties;
import java.sql.*;

public class DatabaseSelect {

public static void main(String[] args) {
System.out.println("Connected to the database!");
Connection conn = null;
String url = "jdbc:oracle://localhost:1571/";
String dbName = "jdbc";
String driver = "com.oracle.jdbc.Driver";
String userName = "HR";
String password = "database";
String query = "SELECT * FROM HR";

try {
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url+dbName,userName,password);
System.out.println("Connected to the database");

} catch (Exception e) {
e.printStackTrace();
}
}
}{code}
