Try calling IBM Watson Assistant 2018-07-10 from the Java SDK.

In Watson Assistant 2018-07-10, you can specify "Option" etc. as the response type. "Option" is like a radio button in HTML, and it is a function that allows you to easily create choices such as three choices and four choices.

What if I call it from the Watson API Java SDK? I tried. In conclusion, it seems that the SDK at the time of writing is not yet compatible with new features. Previously it was returned as text [], but it seems to be returned as generic. It looks like we need to parse the raw JSON.

		System.err.println("---");

		System.err.println(response.getOutput().getText());
