❌ 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.

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.
What Is Bitcoin?
Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
