Which of the statements about this program is correct?
❌ A. It compiles and prints 14 ❌ B. It compiles and prints 15 ❌ 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 6 ❌ F. None of the above
Explanation: The inherited interface method getNumOfGills(int) is implicitly public; therefore, it must be declared public in any concrete class that implements the interface. Since the method uses the default (package-private) modifier in the ClownFish class, line 6 does not compile, making option E the correct answer. If the method declaration was corrected to include public on line 6, then the program would compile and print 15 at runtime, and option B would be the correct answer.

How to Buy Bitcoin?
Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
