Hej,
Question 49, Test 2, a) option said
File f = new File("x");   //1 will throw an exception at runtime if a file named "x" does not exist.
answer is:
You can always create a File object whether or not an actual file or directory by that name exists.
I have just create:
File f = new File("C:\\example.txt"); I do not have this on my disc and I receive exception.
Do you agree with me that it is mistake in this test?
The next option in test is also good but If I have to choose one I choose this.
Please help me.

No, the explanation is correct. Please post exact and complete code that you have tried and the output that you have received.

thank you,
Paul.

Hi I copied and compiled the question and I receive the following compilation error:

TestClass.java:9: error: no suitable constructor found for PrintWriter(FileReader)
PrintWriter pw = new PrintWriter(new FileReader(f)); //4
^
constructor PrintWriter.PrintWriter(Writer) is not applicable
(argument mismatch; FileReader cannot be converted to Writer)
constructor PrintWriter.PrintWriter(OutputStream) is not applicable
(argument mismatch; FileReader cannot be converted to OutputStream)
constructor PrintWriter.PrintWriter(String) is not applicable
(argument mismatch; FileReader cannot be converted to String)
constructor PrintWriter.PrintWriter(File) is not applicable
(argument mismatch; FileReader cannot be converted to File)

Yes, that is expected. That is why option 3 and 4 are incorrect. Explanation to option 3 says the same thing.
Paul.
