Answer 1

import java.util.List;

import java.util.ArrayList;

public class ListTest {

public static void main(String[] args) {

List<String> conversation;

conversation = new ArrayList<String>();

conversation.add("hello");

conversation.add("goodbye");

conversation.add("how are you");

conversation.add("see you later");

for (String element: conversation) {

System.out.print(element + ", ");

}

}

}

Step-by-step explanation:

I used the add method in the code above to add the necessary components to the discussion list. By designating the List as ListString>, I also indicated that the elements to be added to the list are of type String. I printed each element of the list after a ", " at the end after looping through it.
