Display the series 2 + 4/2! + 8/3! + 16/4! + …..+ 2^n/n!

This is a series program using BlueJ. Here 2,4,8 are 2¹_,  2²_, 2³

Write this program using

n: stores the number of terms

s: double type variable to store sum of series

Exponent value is 2

import java.util.*;

class Search

{

    long n;

    double s;

    Scanner sc=new Scanner(System.in);

public void assign()

{   

System.out.print("\nEnter the values of 'n':");

n=sc.nextLong();

}

public void display()

{

    for(long i=1;i< =n;i++)

    {

         s=s+Math.pow(2,i)/fact(i);

    }

    System.out.print("\nSum of the series = " + s);

  

}

public long fact(long x)

{

     long f=1;

for(long i=1;i< =x;i++)

f=f*i;

return f;

}

    public static void main(String args[])

    {

        Search ob=new Search();

        ob.assign();

        ob.display();

   }

 }
