About this code
This code shows you how to use the Java API for the Watson Personality Insights service. Given some text, Watson analyzes the openness, conscientiousness, extraversion, agreeableness, emotional range, and needs of the speaker.
The code has three basic sections:
- Default values for the parameters. These are always used by the
public static void main(String args)method. If the call to
public static JsonObject main(JsonObject args)has no parameters or the wrong number of parameters, the default values are used there as well.
public static void main(String args)method. This uses a
JsonParserto convert the default parameters into a JSON object, then it calls...
public static JsonObject main(JsonObject args)method. This is the action the IBM Cloud Functions platform invokes once the code is deployed.

Lines 69-88 illustrate the Java API for the service. The results include a comment from Watson about the text along with the personality data Watson inferred from it. The Watson SDK wraps the JSON returned by the service as a set of objects that are easy to work with in Java. See the overview of the Watson Personality Insights service or the github repo for the Java API for more information.

Using this code once deployed
To use this code once you've deployed it, you must create an instance of the Watson Personality Insights service:
To invoke the code, pass a JSON structure that matches the
data object as shown above with the following changes:
