Write a recursive method to compute the factorial of a number.
Recursive Method
A technique in programming where a method calls itself to break down complex problems into simpler ones, utilizing a different angle from its first explanation.
Factorial
A mathematical operation that involves multiplying a number by every number less than it down to 1; e.g., the factorial of 5 (denoted as 5!) is 120.
- Employ recursive strategies to address challenges through the development of recursive functions, such as those for computing factorials and powers.

Final Answer :
public static int factorialint n)
{
ifn < 0)
{
System.out.println"Sorry negative numbers not allowed.");
System.exit0);
}
ifn == 1)//base case
return1);
else
return n * factorialn-1));
}
{
ifn < 0)
{
System.out.println"Sorry negative numbers not allowed.");
System.exit0);
}
ifn == 1)//base case
return1);
else
return n * factorialn-1));
