I'm required to send ~100 requests HTTP requests and do some processing with the results of all HTTP requests I have sent. I want to send my HTTP requests parallelly and wait until all the results are back in order to do my process. I am quite new to Java and I'm having difficulty with the approach to this. Kindly suggest a good approach or pattern.

    Http is synchronous. Only thing you can do is the processing of those 100 tasks (request) processesing (individual sending + receiving + processing) async using Future Task and executor framework on threads. Here is a example https://www.baeldung.com/java-future – Sachin May 30 '21 at 09:19
