Convert an Iterator to Stream in Java
At first, set an Interator −
Iterator<Integer>iterator = Arrays.asList(50, 100, 200, 400, 500, 1000).iterator();
Now, we have used stream −
Stream<Integer>stream = convertIterator(iterator);
Above, the method convertIterator() is used for conversion. Following is the method −
public static <T> Stream<T>
convertIterator(Iterator<T> iterator) {
return StreamSupport.stream(((Iterable) () -> iterator).spliterator(), false);
}Example
Following is the program to convert an Iterator to Stream in Java −
import java.util.stream.*;
import java.util.*;
public class Demo {
public static <T> Stream<T>
convertIterator(Iterator<T> iterator) {
return StreamSupport.stream(((Iterable) () -> iterator).spliterator(), false);
}
public static void main(String[] args) {
Iterator<Integer>iterator = Arrays.asList(50, 100, 200, 400, 500, 1000).iterator();
Stream<Integer>stream = convertIterator(iterator);
System.out.println("Iterator to Stream...");
stream.forEach(s -> System.out.println(s));
}
}Output
Iterator to Stream... 50 100 200 400 500 1000
