int[] array = {6,9,8}; List<Integer> list = new ArrayList<>(); list.add(array[0]); list.add(array[2]); list.set(1, array[1]); list.remove(0); System.out.println(list);
❌ A. [8] ✅ B. [9] ❌ C. Something like [Ljava.lang.String;@160bc7c0 ❌ D. An exception is thrown. ❌ E. The code does not compile.
Explanation: The array is allowed to use an anonymous initializer because it is in the same line as the declaration. The ArrayList uses the diamond operator allowed since Java 7. This specifies the type matches the one on the left without having to re-type it. After adding the two elements, list contains [6, 8]. We then replace the element at index 1 with 9, resulting in [6, 9]. Finally, we remove the element at index 0, leaving [9]. Option C is incorrect because arrays output something like that rather than an ArrayList.

Secret Chats are one of the service’s additional security features; it allows messages to be sent with client-to-client encryption. This setup means that, unlike regular messages, these secret messages can only be accessed from the device’s that initiated and accepted the chat. Additionally, Telegram notes that secret chats leave no trace on the company’s services and offer a self-destruct timer.
