[docs] Cover naming of Channel ID (#1492)

Make the Java naming convention more clear, as 100% of the new binding submissions that I have looked in the last week have all failed to know this.

+    * Variables: `lowerCamelCase`
+    * Constants: `ALL_UPPER_CASE`
 - Generics must be used where applicable. See example below:
