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

Quick solution:

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

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

Syntax:

Arrays.stream(arrayName, indexStart, indexEnd);

Code example: 

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);
    }
}

Output:

C
D
