Oracle Exam 1Z0-809 Topic 14 Question 65 Discussion

Actual exam question for Oracle's 1Z0-809 exam
Question #: 65
Topic #: 14
[All 1Z0-809 Questions]

Given the code fragment:

public static void main (String[] args) throws IOException {

BufferedReader brCopy = null;

try (BufferedReader br = new BufferedReader (new FileReader(''employee.txt''))) { //

line n1

br.lines().forEach(c -> System.out.println(c));

brCopy = br;//line n2

}

brCopy.ready(); //line n3;

}

Assume that the ready method of the BufferedReader, when called on a closed BufferedReader, throws an exception, and employee.txt is accessible and contains valid text.

What is the result?

Haha, this question is like a game of BufferedReader roulette! I think the answer is D, but I wouldn't be surprised if the exam gods throw us a curve ball. Gotta stay on our toes, folks!

Whoa, this is a tricky one! My money's on D. The code will print the file and then throw an exception when we try to use the closed BufferedReader. Gotta love those try-with-resources blocks!

Yeah, I agree. The code will print the file and then throw an exception at line n3.

Haha, this question is a real brain-teaser! I'd say the answer is C. The code is trying to assign a closed BufferedReader to the brCopy variable, which should result in a compilation error.

I think the answer is A. The ready() method is being called on a closed BufferedReader, so it should throw a compilation error at line n3.

That makes sense. It's important to remember the behavior of methods when working with BufferedReader.

Yes, you're right. Calling ready() on a closed BufferedReader will indeed result in a compilation error at line n3.

I agree with you, it should be D. The code will print the content of the file before throwing an exception at line n3.

The correct answer is D. The code will print the content of the employee.txt file and throw an exception at line n3. This is because the BufferedReader is closed at the end of the try-with-resources block, but we're still trying to call the ready() method on the brCopy reference, which will result in an exception.
