[Java] How to compute sum of all elements from an array?

We can use the streams to do this. Folling code shows how to do that

import java.util.Arrays;

public class JavaArrays {
	public static void main(String[] args) {
		int[] numbers = {45, 22, 67, 90 };
		System.out.println("Sum of all elements is: " +  Arrays.stream(numbers).sum());
	}
}

Output:

Sum of all elements is: 224
