Question

Given a string containing space-separated integer values, compute the sum of those values. Each string will contain at least one number. sumString("1 2") → 3 sumString("1 2 3") → 6 sumString("7 -7 0 59") → 59 int sumString(String str) {    }

Answer 1

public class SumString {

    int sumString(String str) {
        int sum = 0;
        String[] words = str.split(" ");
        for (int i = 0; i < words.length; i++) {
            sum += Integer.parseInt(words[i].trim());
        }
        return sum;
    }

    public static void main(String[] args) {
        System.out.println(new SumString().sumString("1 2"));
        System.out.println(new SumString().sumString("1 2 3"));
        System.out.println(new SumString().sumString("7 -7 0 59"));
    }
}
