Java is often regarded as a top choice for IoT systems development due to its platform independence, robustness, and security features. Its "write once, run anywhere" (WORA) capability ensures that IoT devices across different environments can easily run Java applications. Additionally, Java's extensive library support, efficient memory management, and scalability make it well-suited for managing the large-scale, distributed nature of IoT ecosystems. Furthermore, how does Java's ability to integrate with various protocols and handle real-time data enhance its suitability for IoT systems?
