Java Timer vs ExecutorService?

Question

I have code where I schedule a task using java.util.Timer. I was looking around and saw ExecutorService can do the same. So this question here, hav

Answer 1

ExecutorService is newer and more general. A timer is just a thread that periodically runs stuff you have scheduled for it.

An ExecutorService may be a thread pool, or even spread out across other systems in a cluster and do things like one-off batch execution, etc...

Just look at what each offers to decide.
