Explanations “Top Java Quiz Questions”

What is the output of the program?

❌ A. 12
❌ B. 1234
❌ C. 1235
❌ D. 124
✅ E. 1245
❌ F. The code does not compile
❌ G. An uncaught exception is thrown

Explanation:
The parseName method is invoked within main() on a new Dog object. Line 4 prints 1. The try block executes and 2 is printed. Line 7 throws a NumberFormatException, so line 8 doesn’t execute. The exception is caught on line 9, and line 10 prints 4. Because the exception is handled, execution resumes normally. parseName runs to completion, and line 17 executes, printing 5. That’s the end of the program, so the output is 1245.
