EventBus vs guava: What are the differences?

**Introduction**
This Markdown code snippet will outline the key differences between EventBus and Guava.

**1. Event handling**:
EventBus focuses on event-driven architecture, enabling decoupling of components by using publish-subscribe design. Guava, on the other hand, provides utilities for basic event bus functionality but does not have the same level of event handling features as EventBus.

**2. Dependency**:
EventBus is a standalone library specifically designed for event bus functionality, while Guava is a more extensive library that includes various utilities and data structures in addition to event bus capabilities.

**3. Customization**:
EventBus allows for customizable event delivery mechanisms, such as specifying different thread execution policies. Guava, on the other hand, has limited customization options for event handling.

**4. Community support**:
EventBus has a dedicated community that focuses on event-driven development and provides regular updates and support. Guava, though widely used, may not have the same level of community support and resources specifically for event handling.

**5. Extensibility**:
EventBus offers more extensibility options for adding custom functionality and integrating with other libraries, making it a preferred choice for complex event-driven systems. Guava, while versatile, may have limitations when it comes to extending event bus capabilities.

**6. Performance**:
EventBus is optimized for efficient event delivery and processing, making it suitable for high-performance applications. Guava, while efficient, may not have the same level of performance optimizations specifically tailored for event handling scenarios.

In Summary, this Markdown code snippet highlights the key differences between EventBus and Guava, focusing on event handling, dependency, customization, community support, extensibility, and performance.
