What is the output of the following code? (Choose all that apply)
❌ A. 2 ❌ B. 4 ✅ C. The code will not compile because of line 3. ✅ D. The code will not compile because of line 5. ✅ E. The code will not compile because of line 7. ❌ F. The code will not compile because of line 11. ❌ G. The output cannot be determined from the code provided.
Explanation: First, the method getTailLength() in the interface HasTail is assumed to be public, since it is part of an interface. The implementation of the method on line 3 is therefore an invalid override, as protected is a more restrictive access modifier than public, so option C is correct. Next, the class Cougar implements an overloaded ver- sion of getTailLength(), but since the declaration in the parent class Puma is invalid, it needs to implement a public version of the method. Since it does not, the declaration of Puma is invalid, so option D is correct. Option E is incorrect, since Puma is marked abstract and cannot be instantiated. The overloaded method on line 11 is declared correctly, so option F is not correct. Finally, as the code has multiple compiler errors, options A, B, and G can be eliminated.

However, analysts are positive on the stock now. “We have seen a huge downside movement in the stock due to the central electricity regulatory commission’s (CERC) order that seems to be negative from 2014-15 onwards but we cannot take a linear negative view on the stock and further downside movement on the stock is unlikely. Currently stock is underpriced. Investors can bet on it for a longer horizon," said Vivek Gupta, director research at CapitalVia Global Research.
How to Use Bitcoin?
n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
