If a file is opened for reading and the file does not exist, what action is taken?

A) A new file is created.

B) A NULL value is returned.

C) An error message is issued.

D) An EOF value is returned.

C) An error message is issued.

Explanation:

If we try to open a file for reading when that file does not exist, we will get an error message.

For example, in Java we will encounter a FileNotFoundException as in the code below:

try {

FileInputStream fis = new FileInputStream ("myFile. txt");

DataInputStream dis = new DataInputStream (fis);

BufferedReader br = new BufferedReader (new InputStreamReader (dis));

String str = null;

while ((str = br. readLine ()) ! = null) {

System. err. println (str);

}

} catch (FileNotFoundException e) {

e. printStackTrace ();

}

If the file myFile. txt does not exist we can expect to see an exception stack trace corresponding to FileNotFoundException.
