Add batch functionality to Java Project

Closed

Description

Hello,

I currently have a Java project that creates hash functions and inserts the hash values into a database.

What I require is to batch process this, so for all the files it will run the first hashing algorithm (MD5) then record the time taken, then run the second hashing algorithm (SHA-1) store the time taken, etc. The time needs to be outputted into a table or CSV

Each new hashing algorithm needs a new process ID and/or the RAM needs to be flushed after each algorithm is run. This is because I am having problems with files being stored in RAM which is affecting the time taken for the next test.

All the hashing functionality works fine.

Currently its connected to a mySQL database, I also require it to work with Postgres SQL and MS SQL.
