Help Java

Javafx Write up some simple sample code to demonstrate indirect recursion. You can just use print statements to demonstrate how they call one another.

Answer 1

So the code is:

public class Main {
    public static void main(String[] args) {
        //in this code I will demonstrate a printing countdown from 20 to 1
        //for that passing a number to the function1 a number 20, we could have
        //passed the initial number to any function
        print1(20);
    }
    //this a function which prints indirectly recursively
    public static void print1(int n){
        //function is passed a value n if n is greater than 0
        if(n>0){
            //n is printed
            System.out.println("This was printed from method 1: "+n);
            //print2 method is called and n-1 is passed to that method
            print2(n-1);
        }
    }
    //this is also a function which prints indirect recursively
    public static void print2(int n){
        //if n passed is greater than 0
        if(n>0){
            //it is printed here
            System.out.println("This was printed from method 2: "+n);
            //print1 is called and n-1 is passed this chan continues till any
            //of the function receives 0 and the indirect loop terminates
            print1(n-1);
        }
    }
}
