Why don't you gust return yourPoints > avg?

First i was thinking, the average was not good, then i understand.

Thanks , nice code

I did the same, exept avg calculation. avg /= classPoints.length+1;
did I do wrong?

When calculating average values you need to make sure at least one of the divisors ist double/float because Integer/Long divisions result in integer/long values.

I would have thought the long would coerce the int . . .

Is the data type wrong?

you are lucky this works in this case because you calculated the average wrong. (Integer / Long division)
