Write a program in Java to find the sum of the given series:

2 - 4 + 6 - 8 + …… - 20

public class KboatSeries
{
    public static void main(String args[]) {
        double sum = 0.0;
        for (int i = 1; i <= 10; i++) {
            if (i % 2 == 0) 
                sum -= i * 2;
            else
                sum += i * 2;
        } 
        System.out.println("Sum = " + sum);
    }
}
