Paho Java Client

The Paho Java Client is a software library that allows Java programs to communicate using the MQTT (Message Queuing Telemetry Transport) protocol, which is designed for lightweight, efficient messaging between devices or applications. It enables applications to publish messages (share information) and subscribe to receive messages from other sources, often used in IoT (Internet of Things) setups. By providing this functionality, Paho Java Client helps developers build systems that can send and receive data reliably across networks, even with limited bandwidth or connectivity, making it ideal for real-time data exchange in various applications.
