Program to find the factorial of a number given through the use of command line argument in java code example
Example 1: how to make factorial in java
class fact{
static int fac(int n){
int ans =1;
for(int i=1; i<=n; i++){
ans = ans*i;
}
return ans;
}
public static void main (String[] args){
int f = 5;
System.out.println(fac(f));
}
}
Example 2: factorial program in java
public class FactorialDemo
{
public static void main(String[] args)
{
int number = 6, factorial = 1;
for(int a = 1; a <= number; a++)
{
factorial = factorial * a;
}
System.out.println("Factorial of " + number + " is : " + factorial);
}
}
