Arraylist not displaying the right output

My main class code

{
     ArrayList<Item> items = new ArrayList<Item>();
     Scanner file = new Scanner(kk.class.getResourceAsStream("product.txt"));
     while (file.hasNextLine()) { 
        String[] sp = file.nextLine().split(",");
        // extract item number, description, price and type
        itemNum = Integer.parseInt(sp[0]);
        des = sp[1];
        price = Integer.parseInt(sp[2]);
        Item objt = new Item(itemNum, des, price); // Creating a new object
        items.add(objt); // Adding it to the list
     }
     System.out.println(items);
}

output I am getting

[dada.Item@4a5d4a62, dada.Item@32be8e12, dada.Item@7c6159c4, dada.Item@5b4c92a7, dada.Item@3040c5,

My item class code

 private int itemNum = 0;
private String des = "";
private int price = 0;

public Item(int i, String d, int p) {
    itemNum = i;
    des = d;
    price = p;
}

You're printing the Item reference's address instead of the fields inside your Item object. You have print the fields inside each Item object by looping through them.

Replace this line 

System.out.println(items);

with 

for(Item i : items) 
{
    System.out.println(i.getItemNum()+" "+i.getDes()+" "+i.getPrice());
}

Change the class so that you could access your private fields

private int itemNum = 0;
private String des = "";
private int price = 0;

public Item(int i, String d, int p) {
    itemNum = i;
    des = d;
    price = p;
}

public void setItemNum(int itemNum) {
    this.itemNum = itemNum;
}
public int getItemNum() {
    return itemNum;
}

public void setDes(String des) {
    this.des = des;
}
public String getDes() {
    return des;
}

public void setPrice(int price) {
    this.price = price;
}
public int getPrice() {
    return price;
}
