Java Multithreading and Parallel Programming Masterclass - Project - Parallel Text File Processing

What is the primary function of the program discussed in the lecture?

• To create a backup of files

• To delete files from a directory

• To periodically scan a directory and process new files

• To modify files in place

Which hashing algorithms are mentioned as options for processing file lines?

• SHA-256, SHA-1, MD5

• SHA-512, SHA-3, Whirlpool

• AES, DES, RSA

• Blowfish, Twofish, Serpent

What is the role of the watcher thread in the program?

• To delete processed files

• To process each file line by line

• To monitor the directory and initiate processing threads

• To handle exceptions during file processing

How does the program ensure that each file is processed?

• By using a single thread for all files

• By creating a new thread for each file

• By using a queue system

• By processing files sequentially

What is the purpose of the buffer writer in the file processing logic?

• To read the file content

• To write the processed output to a new file

• To apply the hashing function

• To delete the original file

What is demonstrated when the program is run with multiple files?

• Files are not processed at all

• Files are processed sequentially

• Files are processed by the same thread

• Files are processed in parallel by different threads

What happens when a processing thread encounters an empty line?

• The program crashes

• The line is skipped

• An exception is thrown

• The file is deleted

How does the program handle exceptions in processing threads?

• By using an uncut exception handler

• By logging them to a file

• By terminating the program

• By ignoring them

What is a potential enhancement mentioned for the watcher thread?

• To remove files once processed

• To process files faster

• To use fewer threads

• To handle more file types

What is the main idea behind using multiple threads in this project?

• To simplify the code

• To fan out processing from one thread to multiple threads

• To increase file size

• To reduce memory usage
