I want to know What does the concept of “worker” mean in programming?
I’ve recently started Java and have seen in so many places where they are used but don’t get the idea.
Examples would be great.
A worker is something you give a task and continue in your process, while the worker (or multiple workers) process the task on a different thread. When they finish they let you know about it via a call back method. I.e. a special method provided on the initial call gets called.
