So, I need to download 2 csv files which include pricing details for some AWS services.

https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AWSStorageGateway/current/index.csv
https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonS3/current/index.csv

I need to download the files from the URLs and store it in separate folders to avoid conflicts. Such as, the first index.csv file will be downloaded to a folder AWSStorageGateway and the second one to folder AmazonS3.

Or another approach could be to store those files in 1 folder by changing filenames like AWSStorageGateway.csv and AmazonS3.csv. If the files already exist, it needs to be replaced with the new one.

The project uses Java 8 and Spring MVC. I don't want to use any external libraries. Is NIO package enough to handle this?

I think you can do that in pure java. With spring and nio, you can definitly do this task. – Donatic May 06 '22 at 07:34

@Donatic The Files.copy worked for me. Thanks for that – Ritwik1711 May 07 '22 at 08:23
