Action happened when the user tries to open a file for reading that doesn’t exist: A “FileNotFoundException” would be thrown if the file could not be opened because, there is already a folder named which was given by the user. This exception can be thrown when an application tries to open a file for writing, but that file only for read, or the permissions of the file don’t allow the file to be read by any application. Therefore, Java will throw a “FileNotFoundException” when the user opens a file for reading which doesn’t exist.

A “FileNotFoundException” would be thrown if the file could not be opened because, there is already a folder named which was given by the user.

This exception can be thrown when an application tries to open a file for writing, but that file only for read, or the permissions of the file don’t allow the file to be read by any application.

Therefore, Java will throw a “FileNotFoundException” when the user opens a file for reading which doesn’t exist.

Explanation of Solution

Action happened when the user tries to open a file for writing that doesn’t exist:

The “PrintWriter” class helps to create the object for “PrintWriter” for text file creation and data can be written into that text file.

If the output file already exists, it is emptied before the new data are written into it.

Therefore, Java will create a new empty file when the user opens a file for writing which doesn’t exist.
