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

x - x²/3 + x³/5 - x⁴/7 + …. to n terms

import java.util.Scanner;

public class KboatSeries
{
    public static void main(String args[]) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter x: ");
        int x = in.nextInt();
        System.out.print("Enter n: ");
        int n = in.nextInt();
        
        double sum = 0;
        int a = 1;
        for (int i = 1, j = 1; i <= n; i++, j+=2) {
            double term = Math.pow(x, i) / j * a;
            sum += term;
            a *= -1;
        }
        System.out.println("Sum = " + sum);
    }
}
