Array storing

i want to use an array to store the item from database instead of hard coding the item which is shown at the last part of the code.
When i do a System.out.println(itemName + serialNumber+ carModel + listPrice); , it did show the item from database but when i use an array to store it, it does not show the correct output.WHY???


while (rs.next()) {
for (int i = 1; i <= info.getColumnCount(); i++) {
itemName = rs.getString("itemName");
serialNumber = rs.getString("serialNumber");
carModel = rs.getString("carModel");
listPrice = rs.getDouble("listPrice");

items[i]=new Item(itemName, serialNumber,carModel, listPrice);
System.err.println(items[i]);

}



// private static Item[] items =
// { new Item(itemName,
// "<I>"+carModel+"</I> ",
// specifications,44.44),
//
// new Item("11111",
// "Description","This is a decription",49.95)
// };

I may be wrong but I don't see how this is a Servlet question.

What does it display? Could you post the output here?
What is wrong with what it displays? Could you explain that and describe what it should have output?

hi Nico Yukiko ,
What is the reference type of ur array. btw an array is a collection of same objects. how can u put an double and string in the same array. try rectifying this problem and see how it works.

As a guess, I would say you need to override your Item class's toString() method to output the data in the form you require.

I agree with Norm. Please show us what the above code displays so that we can help you fix it.
