Help . I am having problems
There are 7 errors in this program that I am unable to locate due to inexperience. Please locate and tell me of all 7 errors. Include what the errors are and how to fix them .
// A class that computes the sample statistics of the ages of
// family members.
public class FamilyStats
{
public static void main(String[] args)
{
/*
math equations obtained from: */
Sample Variance  from Wolfram MathWorld
// define some ages
int momsAge= 42; dadsAge= 43;
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: Help . I am having problems
Please use [code] tags [/code] when posting code.
A lot of people here won't bother reading unformatted code.
You also need to post the errors you are getting and what line(s) they are occurring on.
AGain, most people here will not copy/paste code into an IDE to find out where your code is not compiling.Please do not ask for code as refusal often offends.

Re: Help . I am having problems
Exactly what I said.
Look at your second post.
If your code in your original post were wrapped in tags like that then it would retain its formatting.Please do not ask for code as refusal often offends.

Re: Help . I am having problems
I posted every single mistake and I have a feeling that I have done your homework. So I deleted them.
I think those were all syntax errors.
To fix them all read through these : http://docs.oracle.com/javase/tutorial/
By the end you will most probably know what's wrong with the code.Last edited by PhQ; 09262012 at 07:27 PM.

Please go through the Forum Rules  particularly the third paragraph.
