How to find the sum of the absolute values in Java?

To calculate the sum of the absolute values of a set of numbers, you can iterate through the array, take the absolute value of each number one by one, and then add up all the absolute values.

Here is an example code:

public class AbsoluteSum {
    public static void main(String[] args) {
        int[] numbers = {-1, 2, -3, 4, -5};
        int sum = 0;
        
        for (int num : numbers) {
            sum += Math.abs(num);
        }
        
        System.out.println("绝对值之和为：" + sum);
    }
}

The output is: The sum of the absolute values is 15.

In the above code, we utilized the Math.abs() method to obtain the absolute value of each number and added them together in the variable sum. Finally, we printed the value of sum as the sum of absolute values.
