public class Series

{

public static void main()

{

Scanner sckyu = new Scanner(System.in);

int i,j,n;

double s;

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

n=sc.nextInt();

{

for(i=2;i<n;i++)

if(i%2==0)

i++;

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

if(i%2!=0)

j++;

}

s=i/j;

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

}

}

Answer 2

Question:

Write a program in java to print the series upto n terms_

$S = \dfrac{2}{1} + \dfrac{4}{3} + \dfrac{6}{5} + ...... n.$

Answer:

import java.util.*;

{

public static void main(String args[])

{

Scanner in =new Scanner(System.in);

int a,b,n;

float S=0.0;

n= in.nextInt();

for(a=2;a<=n;a=a+2)

for(b=1;b<=n;b=b+2)

{

S= S+(a/b);

System.out.println("The series is="+S);

}
