Assignment 3 In this assignment you will practice file input and output. You are given two options: those who think up to 60% is enough for them, solve the first part. Those who think they are to get full point, continue with the second part Part1 (basic: 60%) We have already seen how to copy a file using java. Utilizing that knowledge write a program that given a list of files (names) and the destination (all through command line input as executing the program), it will copy all those files into the destination folder. Note: if a specified path is a directory, mention that it is a directory, and skip copying it. Note: handle all the possible exceptional cases and user error. Note: every time a file is copied, print the number of bytes copied. Example: if file size is 36 bytes, print 36 B. if file size is 3635 bytes, print 4 KB. if file size is 3635124 bytes, print 4 MB. Part2 (medium: 40%) Given a list of directories and files followed by the destination copy all these directories(recursively) and files into the destination. Note: all the subdirectories and files inside the given directories must be kept in the same nested structure in destination folder.
Assume that the folder structure is as following: (use tree IF command to see the directory structure recursively, just tree on Mac or Linux) dest resources docs -books some citations.txt american London BEFORE ADAM.txt THE IRON HEEL.txt The People of the Abyss.txt -russian -Dostoevsky The Gambler.txt THE POSSESSED (The Devils).txt -Tolstoy MASTER AND M.Et -personal doc.txt doc2.txt Sened.docx adal.12 పదవ7.jpg download (1).jpg download.jpg Part1: Executing Java YourAppName "resources/img/ada 1.jpg" "resources/docs/books/some citations.txt" Output >Started: resourceslimglada1.jpg... >Finished FILE: resourceslimglada 1.jpg >Total 11KB were copied! >Started: resources docs\books some citations.txt... >Finished FILE: resources docs books some citations.txt >Total 435B were copied! -dest ada1.jpg some citations.txt Produces a dest) folder structure: Note: as you see, only the specified file(s) (not their paths) are created in the destination folder. a
