Here is what I have so far:

Code:
public class DataTypes
{
public void changeTypes()
{
int intVar = 89;
int doubleVar = intVar;

System.out.print((double)doubleVar);
}
}

Next, I'm to add another method called calcAvg but I'm not sure where I'm supposed to put it, what's proper. I don't recall doing this before and I didn't bring my 15 pound book with me ().

this is assuming that you're passing in an array of doubles. you put it above the public void changeTypes() method.

Code:

public static double calcAvg(double[] nums)
{
double hold = 0;
for ( int i = 0; i < nums.length; ++i )
hold += nums;

hold = hold / nums.length;
return hold;
}

then to call it youd just do

Code:

double[] nums = {1,2,3,4,5}; //creat teh array
double avg = calcAvg(nums); //call the function and let avg equal what's returned from it

Wow, whoa, I think that's...too advanced... I'm still in Programming for Info Tech I.

I think I have it now though, thanks anyways for trying.
