import java.util.*;

public class Lautturi {
	public static void main(String[] args) {
		int[] arr = new int[] {1,2,3,4,5};
		int[] newArr = Arrays.stream(arr).map(n -> n * 2).filter(n -> n % 4 != 0).toArray();
		System.out.println(Arrays.toString(arr));
		System.out.println(Arrays.toString(newArr));
	}
}

output:

[1, 2, 3, 4, 5]
[2, 6, 10]
