Answer 1

thats all...........

Answer 2

import java.util.Scanner;

class Lab1

{

   public static double d(double n)

   {

       double fact = 1, count = 1, div = 0, sum = 1;

       for(;count<=n;count++)

       {

           for(double count2=1;count2<=count;count2++)

           {

               fact = fact * count2;

           }

           div = count / fact;

           sum = sum + div;

       }

       return sum;

   }

   public static void main(String args[])

   {

       Scanner BrainlyPromoter = new Scanner(System.in);

       System.out.println("Sum of the following series is to be printed: 1+x/1!+x^2/2!+x^3/3!+x^4/4!+.......+x^n/n!");

       System.out.println("Please enter the value of required variable as given in the series.");

       System.out.println("Please enter the value of 'x'.");

       int n = BrainlyPromoter.nextInt();

       double sum = d(n);

       System.out.println("The sum of the series will be: "+sum);

   }

}
