✅ A. Bird is flying ❌ B. Pelican is flying ❌ C. The code will not compile because of line 4 ❌ D. The code will not compile because of line 5 ❌ E. The code will not compile because of line 9
Explanation: The code compiles and runs without issue, so options C, D, and E are incorrect. The trick here is that the method fly() is marked as private in the parent class Bird, which means it may only be hidden, not overridden. With hidden methods, the specific method used depends on where it is referenced. Since it is referenced within the Bird class, the method declared on line 2 was used, and option A is correct. Alternatively, if the method was referenced within the Pelican class, or if the method in the parent class was marked as protected and overridden in the subclass, then the method on line 9 would have been used.

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
