Java Program for Solving Power Series

A Java Program for solving the power series 1+1/2^2+...+1/n^2.

import java.io.*;
class Series2
{
    public static void main(String args[]) throws IOException
    {
        int n;
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter n value: ");
        n = Integer.parseInt(br.readLine());

        if(n>0)
        {
            float sum=0;
            for(int i=1; i<=n; i++)
                sum=sum+(float)(1)/(i*i);
            System.out.println("Sum of Series:"+sum);

        }

        else
            System.out.println("You Entered the Wrong no.");

    }
}

 OUTPUT:

Enter n value
16
Sum of Series:1.5843465
