first array program quiz

[Mcody2]

I need to know whats wrong with the following lines of code and why. I had this questionn on a quiz today, couldn't answer

int[] hws
int mhw = hws.length
int sum = 0
for(int i = 0; i<hws.lengh; i++)
sum = sum + hws[i]
int avg= sum/mhw

thanks
I am a java n00b

well, when you do the following: int mhw = hws.length, it will cause a compiler error since hws has not been initiated and its length is unknown, which also means that you would have compiler errors with the following also:
i<hws.length
hws[i]

And since you are dealing only w. integers here you will have a truncated, not
rounded answer.

what do you mean by a truncated, not rounded answer?
and thanks for the help everyone is so smart

Consider this:

int x=8;
int y=3;
int z=x/y; // (z=2,6666..... rounded: z=3;)

but the answer is integer truncated so you get 2.0.
To avoid this use doubles or add 0.5 like:
int z=(double)x/(double)y + 0.5d;
