JAVA connessione al DB

[allejo]

Correggo

import java.sql.*;
import java.io.*;
import sun.misc.*;
import java.util.*;

class Connessione {
	
	public Connessione() {
		System.out.println("Connessione al driver...");
		String driverName = "oracle.jdbc.driver.OracleDriver"; 
		String url = "jdbc:oracle:thin:@134.32.232.112:1521:Nome"; 
		String userName = "user"; 
		String password = "pwd"; 
		conn = DriverManager.getConnection(url,userName,password);
	}

	public static void main(String args[]) {
		Connessione connDB = new Connessione();
	}
}

Pero conn come cavolo va dichiarato?

Mi dice questo errore

D:\java\Connessione\Connessione.java:16: cannot resolve symbol
symbol : variable conn
location: class myprojects.connessione.Connessione
conn = DriverManager.getConnection(url,userName,password) ;

Come mai?
