I can't find anything wrong with this but somehow it's wrong.

I'm in an AP CS class and I was given an assignment that required me to find and correct mistakes. I opened the program and it tells me (on BlueJ)after I try to compile it '.class' expected. I haven't gotten that far into my class to know what that means. Can anyone explain. Code:

`public class FamilyStats`

{

public static void main(String args [])

{

/*

math equations obtained from: */

http://mathworld.wolfram.com/SampleVariance.html

// define some ages

int momsAge= 42; int dadsAge= 43; <---This line shows the first problem. 7 in all.

int myAge= 22, sistersAge= 16;

int dogsAge= 6;

// get the mean

double ageSum = (momsAge + dadsAge + myAge + sistersAge + DogsAge);

double average = ageSum / 5

/ calculate the sample variance

double variance= 0.0;

variance += (momsAge - average)*(momsAge - average);

variance += (dadsAge - average)(dadsAge - average);

variance += (myAge - average)*(myAge - average);

variance += (sistersAge - average)*(sistersAge - average);

variance += (dogsAge - average)*(dogsAge - average);

variance = variance / 4;

// get the std. dev

double standardDev= Math.sqrt(variance);

// output the results

System.out.println(The sample age mean is: + average);

System.out.println("The sample age variance is: " + variance);

System.out.println("The sample age standard deviation is: " + standardDev);

}

Re: I can't find anything wrong with this but somehow it's wrong.

-First, take a look at line 7 and 19 and fix the comments :D

-Count the braces

-check upper and lowercase

- ; is necessary in java

- (dadsAge - average)(dadsAge - average) missing sign?

- compare each System.out to the other....

Thanks for the help. I guess I just needed someone lay it out differently.
