# 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
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

 `// 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)> `

Output:

```Sum: 2.708333333333333
```
