Questions 5 - 7 refer to the following code:

public class Whatchamacallit {
private double price;
private String title;

public Whatchamacallit() {
this (0, "none");
}

public Whatchamacallit(double p, String t) {
price = 0;
if (p > 0) {
price = p;
}
title = t;
}

public String toString() {
return title + " costs $" + price;
}
}
The following code segment appears in another class:

ArrayList list = new ArrayList();

list. add(new Whatchamacallit());
list. add(new Whatchamacallit(3.5, "book"));
list. add(new Whatchamacallit(-17, "CD"));
list. add(new Whatchamacallit(18.95, "sweater"));
list. add(new Whatchamacallit(5, "notebook"));

/* Missing Code */
Suppose the following line is used to replace /* Missing Code */.

System. out. println(list. get(list. size() - 1));
What is printed as a result of executing the code segment?

notebook costs $5.0
CD costs $0.0
book costs $3.5
sweater costs $18.95
none costs $0.0

2nd part of question

Suppose the following lines are used to replace /* Missing Code */.

list. remove(1);
System. out. println(list. get(1));

What is printed as a result of executing the code segment?
none costs $0.0
book costs $3.5
sweater costs $18.95
CD costs $0.0
notebook costs $5.0
