How to cite JavaDoc?

Question

Writing a technical Master's degree thesis in the IT field, I need to cite sentences that are in the JavaDoc, where are no author and no year. Ex.

• From: java.util.Queue

  The Queue interface does not define the blocking queue methods, which are common in concurrent programming

• From: org.springframework.boot.actuate.health.HealthIndicator

  Strategy interface used to contribute Health to the results returned from the HealthEndpoint.

Unlike the first one, the second has a base webpage Spring Boot Reference Documentation which shows 14 authors (I know to cite multiple authors). Can be the latter JavaDoc be cited with these authors? How about the first one?

How to cite both of them?

Edit: I have checked the How should I cite a website URL? question, however, the point of my question is that I might cite from multiple classes, where the URL changes. Yeah, little, but still, so it is actually a different source.
