Question

design a class to overloaded function series ( ) as follows:1.double series (doublr n)with one double argument and returns the sum of the series sum=1/1+1/2+1/3+.....+1/n 2.double series (double a ,double n)with two double arguments and returns the sum of the series sum=1/a^2+1/a^5+1/a^8+1/a^11+......+to n terms.


Please answer it very fast ​

Answer 1

1.

import java.io.*;  

  class GFG {  

static double series(double n)  

   {  

     double i, s = 0.0;  

     for (i = 1; i <= n; i++)  

         s = s + 1/i;  

     return s;  

   }  

   public static void main(String args[])  

   {  

       int n = 5;  

       System.out.printf("Sum is %f", series(n));  

         

   }  

}

I don't understand the 2nd question.

Answer 2

Answer:

import java.util.*;

class overload

{

double series (double n)

{

double I,s=0.0;

for(I=1;I<=n,I++)

s=s+1/I;

return s;

}

double series (double a, double n)

{

double I,j,sum=0.0;

for(I=1;I=2;I<=n*3;I+=3;j+=3)

sum=sum+I/Math.pow(a,j);

return sum;

}

}
