Hello !

here is a question to be solved in java :

Write a recursive method called countdown that accepts one integer parameter and prints a rocketship countdown from that number. For example, if the parameter is 5, the output should be 5-4-3-2-1-Blastoff!. You can assume the parameter is non-negative.

here is the code I wrote for it :

public static void countdown (int n ) { if (n == 1) { return"Blastoff!";} else { return n + "" + countdown (n-1);} }

here is the error I get for it :

You didn't declare a method called countdown that has a single int parameter.

The method doesn't contain a recursive call to countdown.

Why am I getting this error ?

Thank you !
