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`][1]

 > The Queue interface does not define the blocking queue methods, which are common in concurrent programming
 - From: [`org.springframework.boot.actuate.health.HealthIndicator`][2]

 > 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][3] 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 [https://academia.stackexchange.com/questions/8098/how-should-i-cite-a-website-url][4] 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.
