+## Programmatic Example of Leader-Followers Pattern in Java
 
-The Leader/Followers pattern is a concurrency pattern where one thread (the leader) waits for work to arrive, de-multiplexes, dispatches, and processes the work. Once the leader finishes processing the work, it promotes one of the follower threads to be the new leader. This pattern is useful for enhancing CPU cache affinity, minimizing locking overhead, and reducing event dispatching latency.

 In the provided code, we have a `WorkCenter` class that manages a group of `Worker` threads. One of these workers is designated as the leader and is responsible for receiving and processing tasks. Once a task is processed, the leader promotes a new leader from the remaining workers.

 This is a basic example of the Leader/Followers pattern. The leader worker processes tasks and promotes a new leader once it finishes a task. The new leader then starts processing the next task, and the cycle continues.
 
-## Applicability

-* Useful in scenarios where programs need to handle multiple services on a single thread to avoid resource thrashing and to improve scalability.

 * [Half-Sync/Half-Async](https://java-design-patterns.com/patterns/half-sync-half-async/): Leader and Followers can be seen as a variation where the synchronization aspect is divided between the leader (synchronous handling) and followers (waiting asynchronously).
 * [Thread Pool](https://java-design-patterns.com/patterns/thread-pool/): Both patterns manage a pool of worker threads, but Thread Pool assigns tasks to any available thread rather than using a leader to distribute work.
