help me with this code

[charles atlas]

can somebody please help me out, i need this code written for a class of mine but Iam completely stumped!
Its gotta be a program that reads in 0 to n floats from the console and calculates the average of the numbers
Any help with those would be GREATLY appreciated

Hi dude man

Welcome to Javaranch. Please read The JavaRanch Naming Policy and change your display name. You can change it here. Thanks.

Regarding your question, we won't write the code for you and deprive you of a learning experience, but if you tell us what you've done, we can give you some hints on how to proceed.

Also, I'm moving this to the Java in General(beginner) forum.

well, i'll give "dude man" (or whatever he is called now ) a start:

public class foo{

public static void main(String[] args){
float total=0;
int i = args.length;
for (int k=0;k<i;k++){
try{
total+=Float.parseFloat(args[k]);
}
catch(NumberFormatException nfe){
;//nothing
}

}
System.out.println(total/i);
}
}

which is not so great. probably what is wanted is an interactive program - it runs, and waits for floats to be entered and return to be pressed till something ("q" or "Q") is entered at which point it kicks back the average. anything not a float but still a number is accepted. anything not a number is rejected. would like to see that myself

much thanks

[peter greaves]

wasn't too bad - hope this helps someone...

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
public class foo{

public static void main(String[] args){
float total=0;
InputStreamReader inreader= new InputStreamReader ( System.in );
BufferedReader breader = new BufferedReader ( inreader );
String s = null;
int counter = 0;

System.out.println("Enter numbers, q to quit...");
try {
   while ( (s = breader.readLine ()) != null ) {
   if (s.equalsIgnoreCase("q")){
   break;
   }
   else{
   try{
      total+=Float.parseFloat(s);
      counter++;   //increment the avg after we know we have a float
}
catch(NumberFormatException nfe){
String bad = (s.length()>0)?s:"CR";
System.out.println(bad  +" isn't a float");
}
}
   }
}
catch ( IOException ioe ) {
   ;//nothing
}
if (counter==0){
System.out.println(0.0f);
}
else{
System.out.println("Average = " + total/counter);
}
}
}

Hmmmm... this assignment looks amazingly familiar.

^^^^^there we go^^^^^
im not albanian, im not thai, and im not chinese. So who am i???
the assignment was too hard for me, so why not ask a fellow grenhorn for some help?
hope you dont mind

[sona gold]

u don't need so many import statements
u can just say import.java.io.*;

Not at all! I told you guys to use JavaRanch as a resource.

peter greaves- I'am trying out your code and i can input numbers but not average them...
tom paul- ok, didn't want to get you mad or anything!

[charles atlas]

wait, nevermind, i figured it out
