Java Program to Find sum of Series with n-th term as n^2 – (n-1)^2

To find the sum of such series, the Java program is as follows −

Example

public class Demo {
   static long my_val = 1000000007;
   public static long compute_val(long my_int){
      return ((my_int % my_val) * (my_int % my_val)) % my_val;
   }
   public static void main(String[] args){
      long my_int = 45687234;
      System.out.println("The computed value is ");
      System.out.print(compute_val(my_int));
   }
}

Output

The computed value is
335959495

A class named Demo defines a function named ‘compute_val’ that computes and returns the sum of a specific series. In the main function, the long integer is defined and the function is calling by passing this integer as the parameter. Relevant output is displayed on the console.
