Question

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

class Test { // class to call recurring functions

        public void recur1(int n) {
                if (n < 0) {
                        return; // base condition
                } else {
                        System.out.println("Calling recur2");
                        recur2(--n); // calling indirect recursion
                }
        }

        public void recur2(int n) {
                if (n < 0) {
                        return; // base condition
                } else {
                        System.out.println("Calling recur1");
                        recur1(--n); // calling indirect recursion
                }
        }

        public static void main(String[] args) {
                Test t = new Test(); // creating an instance of Test class
                t.recur1(5);
        }

}
