Java program for file processing.
Java
READ THE BELOW INSTRUCTIONS.
Note: The code should be a working solution. Do not provide half a solution. Please make sure the entire code is visible in the post and not just a part of the code. The code is executing without any compiler errors. Include the screenshot of the execution. Otherwise, I will downvote because this is the third time I am asking the same question and getting only half solution which is not acceptable.
1] Modularise the code and write Junit tests
2] Use design pattern suitable.
3] Concurrent calls handling - Synchronization
4] Tradeoff between speed and storage of file information
5] If you used list not Set , then why set etc.
Given a list of [FileName, FileSize, [Collection]] - Collection is optional, i.e., a collection can have 1 or more files. Same file can be a part of more than 1 collection.
How would you design a system?
To calculate total size of files processed.
To calculate Top K collections based on size.
Example:
file1.txt(size: 100)
file2.txt(size: 200) in collection "collection1"
file3.txt(size: 200) in collection "collection1"
file4.txt(size: 300) in collection "collection2"
file5.txt(size: 100)
Output:
Total size of files processed: 900
Top 2 collections:
collection1 : 400
collection2 : 300
