How can I call 3 REST endpoints at the same time?

Question

I need to call the REST endpoints A, B and C at the same time and combine the received JSON from each into one JSON. All REST endpoints are on different servers.

My initial project calls 3 Callables that run through FutureTasks. Then I will do Future.get (1000ms) in each FutureTask until they return a value. So will you solve this problem?

Answer 1

This is how I do it. I really like the future interface .
