Answer:
The main method should simply terminate if the FileNotFoundException occurs.
Explanation:
Considering the full code snippet
snippet:public static void main(String[] args) throws FileNotFoundException
public static void main(String[])
represent the entry point method to a java main method
The addition of
throws FileNotFoundException
widens the scope of the main method to explicitly specifies that an exception named the FileNotFoundException may be thrown.
So, if any part of the code explicitly throws the FileNotFoundException the compiler makes use of this to throw an exception.
By throwing an exception, the main method is not catching any exceptions, instead it handles the FileNotFoundException by throwing it to the source which invoked the main method
This is required by the compiler to terminate the program if the FileNotFoundException occurs.
<u>Answer is:</u>
E). They monitor email traffic.
<u>Explanation:</u>
Track Your Device's IP Address with mail. If your laptop or smartphone was stolen, you can use a service like mail to find the IP address of your thief. When you log into those services from any computer, it logs the IP address used, and displays your last used IP in your account. So, these are source for finding the stolen laptop and smartphones.
I hope you got the idea. Thanks
Answer:
B. root
Explanation:
Every user in Linux is assigned a folder from which they can store their files. The interpreter allows you to abbreviate your route with the “~” symbol. The ls command without any additional data shows the files in the current directory, but if after the name of the command a path is written, it shows the files in that path. Therefore, the ls ~ command shows the files in the user's folder.
In addition to the folders and files created by the user or programs, every Linux folder has two subfolders defined by default:
“..”: It is the top level folder in the file hierarchy that contains it. This subfolder is also present in the root of the filesystem (the folder with absolute path “/”), but points to itself.
“.”: It is the folder itself that appears as if it were also a subfolder. It can be considered as a "self-reference" or pointer to itself.
These folders are normal folders in the system for all purposes; that is, they can be used on routes. For example, the path /dirA/dirB/dirC/../fichero2.txt refers to the file that is stored in the dirB folder, since from dirC, the folder .. points to its predecessor, dirB. The following figure shows the interpretation of this route as well as the equivalent of the “..” and “.” Folders.
