In this example, we create the IntConsumer interface and iterate over them with forEach().

Java 8 IntConsumer Example

import java.util.Arrays;
import java.util.function.IntConsumer;

public class JavaForEachConsSpec {

    public static void main(String[] args) {

        int[] inums = { 3, 5, 6, 7, 5 };
        IntConsumer icons = i -> System.out.print(i + " ");
        Arrays.stream(inums).forEach(icons);
    }
}

Output:

3 5 6 7 5
