-## Intent
+## Intent of Active Object Design Pattern
 
-The Active Object design pattern provides a safe and reliable way to implement asynchronous behavior in concurrent systems. It achieves this by encapsulating tasks within objects that have their own thread and message queue. This separation keeps the main thread responsive and avoids issues like direct thread manipulation or shared state access.

+## Programmatic Example of Active Object in Java
+
+This section explains how the Active Object design pattern works in Java, highlighting its use in asynchronous task management and concurrency control.
 
 The Orcs are known for their wildness and untameable soul. It seems like they have their own thread of control based on previous behavior. To implement a creature that has its own thread of control mechanism and expose its API only and not the execution itself, we can use the Active Object pattern.

-## Applicability
+## When to Use the Active Object Pattern in Java
 
-* When you need to perform long-running operations without blocking the main thread.
+Use the Active Object pattern in Java when:
+
+* when you need to handle asynchronous tasks without blocking the main thread, ensuring better performance and responsiveness.
 * When you need to interact with external resources asynchronously.
 * When you want to improve the responsiveness of your application.
 * When you need to manage concurrent tasks in a modular and maintainable way.

 * [Command](https://java-design-patterns.com/patterns/command/): Encapsulates a request as an object, similarly to how the Active Object pattern encapsulates method calls.
 * [Promise](https://java-design-patterns.com/patterns/promise/): Provides a means to retrieve the result of an asynchronous method call, often used in conjunction with Active Object.
 * [Proxy](https://java-design-patterns.com/patterns/proxy/): The Active Object pattern can use a proxy to handle method invocations asynchronously.
