    Default trying to pass default params to tail recursion function

    In this code:

    	public static void main(String[] args) {
    		System.out.println(tailrecsum(5,0));
    	}
     
    	private static int tailrecsum(int x,int running_total, int default_total){
    		if(x == 0){
    			return running_total;
    		}
    		else {
    			return tailrecsum(x-1, running_total+x);
    		}
    	}

    I get an error "The method tailrecsum(int, int, int) in the type MainClass is not applicable for the arguments (int, int)"
    on this line:

    return tailrecsum(x-1, running_total+x);

    I know java doesn't support default parameters, so I use overloading, but not sure why I get the error.

    Default Re: trying to pass default params to tail recursion function

    you define 3 parameters in tailrecsum(int, int, int) but invoke with 2 parameters in return tailrecsum(int, int)
