Specifications on this piece of code

[gio2888]

Can someone tell me if the specifications are correct?

public static double math1(int[] arr){
double sum = 0.0;
for (int i =0; i < arr.length; i++){
sum+ = arr;
}
return sum/ (double)arr.length;
}//end of math1()

Requires: integer array
Modifies: sum
Effects : return average

Look okay to me, although it could use some better formatting. This could also be due to the forum. Are you having problems or just looking for feedback?

I would change the last piece a bit.
Requires: integer array <-- should be int array
Modifies: sum <-- user doesn't need this information it is internal to the method.
Effects : return average <-- should specify the the average returned is of type double Wushutwist

Thanks for the clarifying this for me, I ve been having so much trouble in class figuring what to write in for specifications, but once again thanks!
