Sum up integer values of an int[]-parameter and return the result

Question

How can I sum up the integer values of an int[]-parameter and return the result

Sample1: [1,2,3] must return 6
Sample2: [-7,7,3] must return 3
Sample3: [] must return 0

public static int calculateSum(int[] values) {
        int[] array = {10, 20, 30, 40};
        return Integer.MIN_VALUE;
    }
}

Answer 1

Try this

    public static int calculateSum(int[] values) {
        int result = 0;

        for(int i=0; i<values.length; i++){
            result += values[i];
        }

        return result;
    }
}
