# Java Factorial Program

June 12, 2012 at 5:54 PM

```import java.io.BufferedReader;
import java.io.IOException;

public class Factorial {
public static void main(String args[]) throws IOException {
int num = 0;

num = Integer.parseInt(data);

int result = num;
for (int i = 1; i < num; i++) {
result *= i;
//result = result * i;
}
System.out.println(result);
}

}
```

Output

```Input Any Number
5
120
```

Description:- In the above example find out the factorial of a number. Here, we have used BufferedReader class to input a number to find its factorial. The method readLine() of this class reads the value. As this method returns string type so we have converted it to integer. Then using the loop, we got the factorial of the input number.
