How to generate the series?

[Ajay Bhalala]

Hello all,

I want to generate the following series in the java

1!-2²+3!-4²+5!-6².....

How can I generate this series in Java?

[Luuk]

OK, I have down half of your homework.....

class Series {
            public static void main(String[] args) {
                            System.out.println("Hello World!"); // Display the string.
                            int x=1;
                            double s=0;

                            while (x<10) {
                                    s = s + factorial(x);
                                    s = s - Math.pow((x+1),2);
                                    x = x + 2;
                                    System.out.println(s);
                            }
      }

      public static int factorial(int x) {
              switch (x) {
                      case 1: return 1;
                      case 3: return 6;
                      case 5: return 120;
                      case 7: return 5040;
                      case 9: return 362880;
                      default: System.out.println("Create your own factorial function....."); return 0;
              }
      }
}

and i'm not even a java programmer..... .
