Explain the importance of handling exceptions when working with files. How can unhandled exceptions impact the reliability of file-based applications?

What is the major drawback of a write lock?

Please include the names of the three distinct exception-handling processes.

linux !#bin/bash Backup Files Write a bash script to backup files. The script can take 0, 1 or 2 arguments. When there are 0 or more than 2 arguments, the script should print out the usage of the program on the screen. When there is 1 argument, the program should take the argument as source directory and backup all the files (not include directories) in the source directory. If the source directory does not exist, the program should print out the error message and the usage of the program on the screen. If the source directory exist, create a subdirectory inside source directory named ”backup-yyyy-mm-dd” and copy all the files in source

Help writing a Java program (please provide photos it works so I'm not studying a nonworking program) Write a complete version of the Bresenham Midpoint algorithm to handle ALL slope values.  Include appropriate tests for ‘special case’ conditions.  Instead of “WritePixel” write to the screen the coordinates of the pixel that would be drawn.  Your program must implement the algorithm given in class with modifications to handle the special cases. Different slope values: m = 0, m = 1, m = > 1, m = infinity (needs special test case) , m < 0 (swap x and y) The user should be able to enter coordinates and it should output the coordinates it takes to draw from the first point to the last point
