How to Reuse Stream Data in Java 8 Without Creating Collections?

Duplicating Streams Without Creating Collections

In Java 8, using streams provides significant optimization benefits if you intend to use the data only once. However, if you wish to reuse the same data, you must either generate it multiple times or store it.

Initially, it was proposed to integrate "forked streams" into the stream design. However, supporting this feature burdened the common case (one-time usage) at the expense of the uncommon case (multiple usage).

Consider using Consumers if you want to apply multiple operations on the same data:

<code class="java">stream()...stuff....forEach(e -> { consumerA(e); consumerB(e); });</code>

Additionally, you can explore the RxJava library, which offers a processing model more suited to "stream forking."
