public static void main(String args[])
{
int num = 5;
int result = 1;
int result2 = 1;
//using while loop
while(num>0)
{
result = result * num;
num--;
}
//using for loop
num = 5;
for(int i=num;i>=1;i--)
{
result2=result2*i;
}
System.out.println("Factorial of Given no. is : "+result);
System.out.println("Factorial of Given no. is : "+result2);
}
}
