Java: Templates for monitoring workflows?

Question

and excuse the lack of knowledge about multithreaded applications, but I'm new to this field.

Is there a template or common methodology used to monitor the “job completion” or “job status” of workflows from the monitor (a class that acts like a monitor)?

I am currently creating a list of workers and creating one thread for each worker. After all the threads are started, I iterate over the worklist and check their status by making a method call.

At that time, I could not come up with another solution, but as a newcomer to the field, I do not know if this is suitable, or if there are other solutions or templates that I should study.

Try using any synchronization. For example, wait on some monitor / semaphore until the work is done / what you need.
