recursion question java code example

Example 1: recursion in java

class scratch{
    public static long factorial(int n){
        if ( n == 1 ){
            return 1;
        }
        else{
            return n * factorial( n - 1 );
        }
    }
    public static void main(String[] args) {
        System.out.println( factorial(5) );
        //Print 120 (5!) to the console
    }
}

Example 2: java recursion

// prints x number of $
public static void recursion(int x) {
  if(x == 0) { // base case
    System.out.println();
  } else { // recursive case
    System.out.print("$");
    recursion(x - 1);
  }
}
