"root","admin");
System.out.println("Connected to the database");

Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
String sql = "select * from sakila.actor";
ResultSet rs = stmt.executeQuery(sql);
while(rs.next()) {
System.out.print("actor_id = "+ rs.getString("actor_id"));
System.out.print(" ; first_name = "+ rs.getString("first_name"));
System.out.println(" ; last_name = "+ rs.getString("last_name"));
