Hi,

Thank you in advance.

I am a beginner using Mattermost.

Inside of our client location, the free software Mattermost is used to send messages

I want to show a demo to my team, how to send a message from java client to mattermost ?

can anyone give me a sample java code that can send message to mattermost ? The mattermost is running on all the devices of our client.

I am using windows 10. So which mattermost I should install to demo on my windows machine ?
