Convert an Iterable to Stream in Java
Let’s say the following is our Iterable −
Iterable<String> i = Arrays.asList("K", "L", "M", "N", "O", "P");
Now, create a Collection −
Stream<String> s = convertIterable(i);
Above, we have a custom method convertIterable() for conversion. Following is the method −
public static <T> Stream<T> convertIterable(Iterable<T> iterable) { return StreamSupport.stream(iterable.spliterator(), false); }
Example
Following is the program to convert an Iterable to Stream in Java −
import java.util.*; import java.util.stream.*; public class Demo { public static <T> Stream<T> convertIterable(Iterable<T> iterable) { return StreamSupport.stream(iterable.spliterator(), false); } public static void main(String[] args) { Iterable<String> i = Arrays.asList("K", "L", "M", "N", "O", "P"); Stream<String> s = convertIterable(i); System.out.println("Iterable to Stream: "+s.collect(Collectors.toList())); } }
Output
Iterable to Stream: [K, L, M, N, O, P]
