Explain Recursion

Recursion: Recursion outcomes from a method being invoked whenever an existing call to the similar method has not yet returned. For example:

    public static void countDown(int n){
        if(n >= 0){
            System.out.println(n);
            countDown(n-1);
        }
        // else - base case. End of recursion.
    }
