# Java Program to find the sum of a Series 1/1! + 2/2! + 3/3! + 4/4! +…….+ n/n!

You have been given a series 1/1! + 2/2! + 3/3! + 4/4! +…….+ n/n!, find out the sum of the series till nth term.

**Examples:**

Input :n = 5 Output : 2.70833 Input :n = 7 Output : 2.71806

`// Java program to print the sum of series` ` ` `import` `java.io.*;` `import` `java.lang.*;` ` ` `class` `GFG {` ` ` `public` `static` `double` `sumOfSeries(` `double` `num)` ` ` `{` ` ` `double` `res = ` `0` `, fact = ` `1` `;` ` ` `for` `(` `int` `i = ` `1` `; i <= num; i++) {` ` ` `/*fact variable store factorial of the i.*/` ` ` `fact = fact * i;` ` ` ` ` `res = res + (i / fact);` ` ` `}` ` ` `return` `(res);` ` ` `}` ` ` ` ` `public` `static` `void` `main(String[] args)` ` ` `{` ` ` `double` `n = ` `5` `;` ` ` `System.out.println(` `"Sum: "` `+ sumOfSeries(n));` ` ` `}` `}` ` ` `// Code contributed by Mohit Gupta_OMG <(0_o)>` |
