JAVA CERTIFICATION QUESTION: Manipulating Java lists—and views of lists

=>Is a list unmodifiable? Is it immutable? What about the views of the list?

· java

Given the following code fragment

String[] arr = new String[] {"A1", "A2"};

List<String> ls = new ArrayList<>();
ls.add("L1");ls.add("L2");

List<String> la = Arrays.asList(arr);
List<String> lf = List.of(arr);
List<String> lc = List.copyOf(ls);
List<String> lu = Collections.unmodifiableList(ls);

arr[1]="A3";
ls.set(1, "L3");

// line n1

System.out.println("la=" + la);
System.out.println("lf=" + lf);
System.out.println("lc=" + lc);
System.out.println("lu=" + lu);

 Which statements are correct? Choose three.

A. The output contains la=[A1, A2]
B. The output contains lf=[A1, A2]
C. The output contains lc=[L1, L3]
D. The output contains lu=[L1, L3]
E. If you add the following at line n1, the output will contain lf=[A1, A3]: lf.set(1, "A3");
F. If you add the following at line n1, the output will contain la=[A1, A3]: la.set(1, "A3");
