What is iterate in stream Java?

You can use stream() method of the List interface which gives a stream to iterate using forEach method. In forEach method, we can use the lambda expression to iterate over all elements. The following code snippet shows the usage of streams to iterate over the list.

Are Java streams iterable?

Even though Stream does not implement Iterable, it has a method iterator() that matches the shape of the abstract method of the Iterable interface. (That is, it takes no arguments, and it returns an Iterator.) So a method reference to the Stream's iterator() method works to implement the Iterable interface.
