In this article, we would like to show you how to create a stream from part of the array in Java 8.

Quick solution:

xxxxxxxxxx
 
String[] letters = new String[]{"A", "B", "C", "D"};
​
// create stream from part array between indexes 2-4
Stream<String> streamOfLetters = Arrays.stream(letters, 2, 4);

Practical example

Edit

In this example, we use Arrays.stream() to create a stream from part of the array.

Syntax:

xxxxxxxxxx
 
Arrays.stream(arrayName, indexStart, indexEnd);

Code example:

xxxxxxxxxx
 
import java.util.Arrays;
import java.util.stream.Stream;
​
public class Example {
​
    public static void main(String[] args) {
        String[] letters = new String[]{"A", "B", "C", "D"};
​
        // create stream from part array between indexes 2-4
        Stream<String> streamOfLetters = Arrays.stream(letters, 2, 4);
​
        // print elements
        streamOfLetters.forEach(System.out::println);
    }
}
