Is Multi-Threaded algorithm required to make use of Multi-core processors?

Question

I was just wondering whether we actually need the algorithm to be muti-threaded if it must make use of the multi-core processors or will the jvm make use of multiple core\'s eve

Answer 1

Your implementation needs to be multi-threaded in order to take advantage of the multiple cores at your disposal.

Your system as a whole can use a single core per running application or service. Each running application, though, will work off a single thread/core unless implemented otherwise.
