Oracle 1Z0-809 Exam - 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?

Compilation error? Nah, it's definitely an exception at runtime.

So, it prints the file and then fails? That's wild!

I’m confused about line n1; I thought it might throw a compilation error, but now I’m leaning towards the exception at line n3 instead.

I practiced a similar question, and I think the code will print the file contents before throwing an exception at line n3.

I’m not entirely sure, but I feel like line n2 might cause a compilation error since brCopy is assigned to a closed resource.

I remember that the try-with-resources statement automatically closes the BufferedReader, so I think line n3 will throw an exception.

This seems like a tricky question that's testing our understanding of resource management and exception handling in Java. I'll need to carefully walk through the code and the given assumptions to determine the most likely outcome.

I'm a bit confused here. The question says the ready() method throws an exception when called on a closed BufferedReader, but it's not clear to me why that would cause a compilation error. I'll need to double-check the Java language specifications on this.

Okay, let me think this through step-by-step. The code is using a try-with-resources block to open the BufferedReader, so it should be automatically closed at the end of the block. But then we're trying to use the brCopy reference after the block, which could be the issue.

I think the key here is understanding the behavior of the try-with-resources block and the lifecycle of the BufferedReader object. If the brCopy reference is still valid after the block, then the code should print the file contents and throw the exception at line n3. But if the brCopy reference is no longer valid, then I'd expect a compilation error at that line.

Okay, I think I've got this. The key is to use a command that can monitor authentications without actually controlling the port. I'm leaning towards option D.

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!

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.

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.
