第六章 數學方程式測試

題目:讓使用者輸入x&n，計算出上列的式子


import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class HomeWork0610 {

public static void main(String[] args)throws IOException{
BufferedReader br= new
BufferedReader(new InputStreamReader(System.in));
System.out.println("請輸入x ");

double x=java.lang.Double.parseDouble(br.readLine());

System.out.println("請輸入n ");

double n=java.lang.Double.parseDouble(br.readLine());

double sum=0;

for(int i=1;i<=n;i++)
sum+=((x+i)/(n-i+1));
if(n==0)
System.out.print("n不可為零");
else
System.out.print(sum);
}
