Try following this tutorial. It should help you understand how to do communication in processes.

Thanks Naill. In the video, communication is implemented through Java Class. Can we do the same using expression? And how can we do that using expression. Any examples?

You can use JavaScript to if you like, it’s more or less the same code and can be embedded into the model like an expression. i think i recall @StephenOTT creating this already

How do I send a message from one process to another?

You have to execute the message through a expression, java delegate, or script. here is a simple example to get you started using a expression: ${execution.getProcessEngineServices().getRuntimeService().createMessageCorrelation("message_bar").correlateWithResult()} see: https://docs.camunda.org/javadoc/camunda-bpm-platform/7.8/org/camunda/bpm/engine/runtime/MessageCorrelationBuilder.html for more API options.
