Printing a method return when using an array as a parameter

[pricklypete]

I'm wondering why my println(arrayAvg()) statements are not producing any results. Could someone point me in the right direction? Below is my program:

This is a sample of the file I'm reading:
STATION DATE PRCP SNOW SNWD TMAX TMIN
----------------- -------- -------- -------- -------- -------- --------
GHCND:USW00014764 20110101 0 0 127 122 -17
GHCND:USW00014764 20110102 5 0 102 67 28
GHCND:USW00014764 20110103 13 0 76 44 -56

	}

	public static double tempConvert(int n) {
		double celsius = (n / 10.0) * 9 / 5 + 32;

You'll need to debug it.
Stick some println()'s in there, to print out what's been read from the file, what the content of the arrays is, what values 'sum' and 'count' are when you do your calculation.
Essentially you need to narrow down where the problem lies.
