❌ A. Orca diving ✅ B. The code will not compile because of line 2 ❌ C. The code will not compile because of line 8 ❌ D. The code will not compile because of line 9 ❌ E. The output cannot be determined from the code provided
Explanation: This may look like a complex question, but it is actually quite easy. Line 2 contains an invalid definition of an abstract method. Abstract methods cannot contain a body, so the code will not compile and option B is the correct answer. If the body {} was removed from line 2, the code would still not compile, although it would be line 8 that would throw the compilation error. Since dive() in Whale is abstract and Orca extends Whale, then it must implement an overridden version of dive(). The method on line 9 is an overloaded version of dive(), not an overridden version, so Orca is an invalid subclass and will not compile.

NEWS: Telegram supports Facetime video calls NOW!
Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
