Saving List<T> as String

I’ve been trying to save a list of data as Strings, but when I try a method .toString on List, it returns address in memory instead of data.

public class Item {

    Integer price = 20;
    Integer modelNumber = 100;
    String description = "Description";
    String title = "Title";
    Boolean wasBought = true;
}
public static void main(String[] args) {
    List<Item> data = new ArrayList<>();
    data.add(new Item());
    System.out.println(data.toString());
}

>Solution :

You need to override toString function in your Item class. Add the following snippet into your Item class:

@Override
    public String toString() {
        return "Item{" +
                "price=" + price +
                ", modelNumber=" + modelNumber +
                ", description='" + description + '\'' +
                ", title='" + title + '\'' +
                ", wasBought=" + wasBought +
                '}';
    }

Output:

[Item{price=20, modelNumber=100, description='Description', title='Title', wasBought=true}]
