The Alexa APIs for Java consists of JAVA POJO classes that represent the request and response JSON of Alexa services. These models act as core dependency for the Alexa Skills Kit Java SDK (https://github.com/alexa/alexa-skills-kit-sdk-for-java ).

This Alexa sample skill is a template for a basic city-guide skill. Provided some data about a city's restaurants, attractions, Alexa will recommend a restaurant based on the meal type or recommend an attraction. It can also suggest the current temperature and weather conditions of the city. This sample Alexa Skill is written in Java and demonstrates the use of external API calls and localization for multiple locale.

Looking at using Alexa voice control to enable outputs and read inputs after login to a client server. Currently the user logs into the server and uses a graphical system to read inputs and enable outputs. The JACE is a Linux based building management controller and i write the logic for this controller. The JACE controller has digital and numeric inputs and outputs that control different areas of a building. The building management controller (JACE which stands for Java Application Control Engine) is fully automated via the control logic i design, but at times set-points need to be adjusted or outputs need to be enabled to override the existing controls. This is done by login to the cloud base server with a username/password and changing a value using a graphical interface. I am designing an Alexa voice control skill to read or adjust temperature settings or switch on a output. Would like to here from anyone with Alexa Skill API knowledge.
