Question:-

Write a java program to find the sum of the series.

S=a/2+a/3+a/4+....+a/n

Program:-

Here is your program written in Java.

import java.util.*;

class SeriesSum

{

public static void main(String args[])

{

double s=0.0, x;

int n, a, i;

Scanner sc = new Scanner(System.in);

System.out.print("Enter the value of n: ");

n=sc.nextInt();

System.out.print("Enter the value of a: ");

a=sc.nextInt();

for(i=1;i<=n;i++)

{

x=a/(double)(i+1);

s+=x;

}

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

}

}
