What is printed besides the stack trace caused by the NullPointerException from line 16?
❌ A. AE ❌ B. AEBCD ✅ C. AEC ❌ D. AECD ❌ E. No output appears other than the stack trace
Explanation: The main() method invokes go and A is printed on line 3. The stop method is invoked and E is printed on line 14. Line 16 throws a NullPointerException, so stop immediately ends and line 17 doesn’t execute. The exception isn’t caught in go, so the go method ends as well, but not before its finally block executes and C is printed on line 9. Because main() doesn’t catch the exception, the stack trace displays and no further output occurs, so AEC was the output printed before the stack trace.

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.”
