how to check the nth factorial or not 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: recursion factorial java
public class Factorial {
public static void main(String[] args) {
int num = 6;
long factorial = multiplyNumbers(num);
System.out.println("Factorial of " + num + " = " + factorial);
}
public static long multiplyNumbers(int num)
{
if (num >= 1)
return num * multiplyNumbers(num - 1);
else
return 1;
}
}
