Recursion

class Factorial {
int fact(int n) {
int result;
if ( n ==1) return 1;
result = fact (n-1) * n;
return result;
}
}
class Recursion {
public static void main (String args[]) {
Factorial f =new Factorial();
System.out.println(“Factorial of 3 is “ + f.fact(3));
System.out.println(“Factorial of 3 is “ + f.fact(4));
System.out.println(“Factorial of 3 is “ + f.fact(5));
}
}
The output from this program is shown here:
Factorial of 3 is 6
Factorial of 4 is 24
Factorial of 5 is 120
