Given the following Java code:

$```$

java

import java.util.ArrayList;

public class ArrayListExample $\{$

public static void main$($String$[]$ args$)\{$

ArrayList names $=$ new ArrayList$()$;

names.add$("$Alice$")$;

names.add$("$Bob$")$;

names.add$("$Charlie$")$;

ArrayList friends $=$ names;

friends.add$("$David$")$;

ArrayList newNames $=$ new ArrayList$($names$)$;

newNames.set$(1,$ "Eve"$)$;

System.out.println$("$names: $"+$ names$)$;

System.out.println$("$friends: $"+$ friends$)$;

System.out.println$("$newNames: $"+$ newNames$)$;

$\}$

$\}$

$```$

$1)$ After executing the above code, what are the contents of names, friends, and newNames? Please explain the changes in the contents of each list.

$2)$ Please explain the relationship between friends and names? Why do changes in friends affect names?

$3)$ Explain why newNames does not affect names? What are the concepts behind this operation?

$4)$ If we want to copy friends without affecting names, what other ways can we achieve this besides using the new ArrayListnames$)$ method?
