Question

What is the output of the following code?

import java.util.ArrayList;

public class ArraylistTest
{
public static void main(String[] args) {
ArrayList craft = new ArrayList ();

craft.add("scissors");
craft.add("paper");
craft.add("glue");
craft.remove("paper");
craft.remove(1);

System.out.println(craft);
}
}

A.
[paper]
B.
[glue]
C.
[scissors]
D.
[craft]

Answer 1

C. [scissors]

Step-by-step explanation:

The given code is a Java program that creates an ArrayList of strings called "craft" and adds three elements to it "scissors", "paper" and "glue". After that the code removes the element "paper" from the list using the method remove("paper"). Then it removes the element of index 1 (which is "glue") from the list using the method remove(1).

After removing the two elements, the list is left with only one element "scissors" which is printed out by the final line of code:

System.out.println(craft);

It's worth noting that the ArrayList stores elements in order, and the elements are indexed starting from 0, so the first element is in the index 0, the second element is in the index 1, and so on.
