Expert Solution & Answer
Chapter 7, Problem 1RE
Explanation of Solution
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.
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.
