Question

Java Program to find the sum of a Series 1/1! + 2/2! + 3/3! + 4/4! +…….+ n/n!

Answer 1

Answer:

This is the required Java program for the question.

import java.util.*;

public class Sum  {

   public static void main(String args[])   {

       double s=0.0,p=1.0,i;

       int n;

       Scanner sc=new Scanner(System.in);

       System.out.print("Enter limit - ");

       n=sc.nextInt();

       for(i=1;i<=n;i++)   {

           p*=i;

           s+=i/p;

       }

       System.out.println("Sum of the series is: "+s);

       sc.close();

   }

}

Algorithm:

• START.
• Accept the limit, say n.
• Initialise s=0, p=1.0, i=1.
• Iterate loop in the range 1 to n.
• Multiply the value of p with loop variable.
• Add the value of i/p to s.
• Display the value of s.
• STOP.
