Streams are a bit more general. They allow you to use functional operations on sequence of elements (e.g. map, filter, reduce, etc.) to build a processing pipeline which can execute async and in parallel. ``` widgets.stream() .filter(b -> b.getColor() == RED) .mapToInt(b -> b.getWeight()) .sum(); ``` https://docs.oracle.com/javase/8/docs/api/java/util/stream/package-summary.html https://docs.oracle.com/javase/8/docs/api/java/util/stream/p... They aren't specific to Java. In fact they require features such as lambdas that made them less practical until Java 8.
