Answer 1

The code will be

import java.util.*;
public class Item {
private String name;
private double price;
private int quantity;
public Item(String n,double p,int q){
name=n;
price=p;
quantity=q;
}
public static void main(String args[]) {
ArrayList<Item> arr=new ArrayList<Item>();
arr.add(new Item("a",1,2));
arr.add(new Item("b",2,2));
arr.add(new Item("c",3,2));
arr.add(new Item("d",4,2));
double total=0.0;
for(Item i:arr){
total+=i.price;
}
System.out.println(total);
}
}

The output is

10.0
