Java MQTT Client with Eclipse Paho

This is a quick post to share a sample code using Eclipse Paho for MQTT.

Recommended: First steps with MQTT using Mosquitto

Some may prefer to use REST  or Websockets, but MQTT is the standard protocol to connect things to the Internet. Even a small NodeMCU can read and publish on MQTT topics. You can configure a RaspberryPi instance to be a mqtt server or even use a cloud MQTT server, such as Paho, Mosquitto and other servers on the cloud. There are also paid services such as Amazon AWS.
