Is it possible to create and infinite stream without limiting the size?

Question

Can we create a Java stream with an infinite source of data (e.g. Health signals)?

Answer 1

Yes.

Of course, limiting the size would cause the stream to be finite.

With, for example, Stream.generate(() -> "tick") you have an infinite stream.

However, the actual implementation heavily depends on the shape of the source. If, for instance, for heart beats, I expect the stream coming from some external device, so then you'll need to setup the transmission as well.
