Java Factorial in Recursion: public int Factorial(int n) { return n * Factorial(n-1); } Boundary conditions in recursion prevent infinite function calls One thing is obviously missing from the code above. If we were to pass in a number, then the function simply will not stop executing!
Enter Number: 5 Factorial is: 120 ExplanationIn the above program, we imported the "java.util.*" package to use the Scanner class. Here, we created a public class Main. The Main class contains two static methods getFactorial(), main(). The getFactorial() is a recursive method that ...
