Consider the list returned by Arrays.asList. Which statement is correct?

  • A.It is immutable.
  • B.It is fixed-size and backed by the array.
  • C.It is an independent ArrayList copy.
  • D.It is fully modifiable.

Answer: B

The javadoc describes it as a fixed-size list backed by the specified array. Structural changes are unsupported optional operations and throw, but set is supported, and writing through it changes the array. Wrapping it in new ArrayList<>(...) is how you get a growable copy.
