## Java program to find sum of factorials from 1 to N

```
import java.util.Scanner;
public class SumOfFactorial
{
public static void main(String[] args)
{
// create scanner class object.
Scanner sc = new Scanner(System.in);
// enter the number.
System.out.print("Enter number : ");
int n = sc.nextInt();
int total=0;
int i=1;
// calculate factorial here.
while(i <= n)
{
int factorial=1;
int j=1;
while(j <= i)
{
factorial=factorial*j;
j = j+1;
}
// calculate sum of factorial of the number.
total = total + factorial;
i=i+1;
}
// print the result here.
System.out.println("Sum : " + total);
}
}
```

## Output

```
First run:
Enter number : 3
Sum : 9
Second run:
Enter number : 5
Sum : 153
```
