Hello,

the following code is not exactly working properly. Bascally when I enter + in the dialog box it escape but still increments in the calculation. So for instance if I first enter a word "hello" then I click OK button then I enter word "there" then I click OK button then I enter + in the dialog box, it will exist the loop but the calcualation still includes the +, as shown shown below

hello has 5 characters
there has 5 characters
+ includes so that is 1 characters 

so in total the it adds to 11, divide by count which gives final answer 3.6666666666666665

when it should be

hello has 5 characters
there has 5 characters

so in total it should be in total 10, divide by count which the final answer should be 5.

Here is my code and I hope I have format the thread correctly. Thanks in advance

 public static double average() 
 { 
     int count = 0; // number of words input
     double Characterscounting = 0;  // total number of characters
     String word = ""; // to hold each word as it is input
     DecimalFormat df = new DecimalFormat("#.#");

     double avg;


      do {
           word =  Dialog.request(" enter next word");
           count++;

          numberOfCharacters = numberOfCharacters + word.length();

           System.out.println(df.format(numberOfCharacters));
           avg =  numberOfCharacters /count; 


          // System.out.println(df.format(avg));

      }   while (!word.equals("+")); // i think here is the problem
                                     // but don't know who to fix it 


       if (word=="*")  // obviously this does not work 
        {
          count = count - 1;
        }

         return avg;  
  }

It looks like you are incrementing the count before checking whether + was entered.
I suggest you simplify your code and use the while loop instead of do..while.

import java.io.*;

public class Main {
    public static void main(String[] args) throws Exception {
        BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
        int words = 0;
        int chars = 0;
        double avg = 0.0;
        while (true) {
            System.out.print("Enter next word: ");
            String word = input.readLine();
            if (word.equals("+"))
                break;
            words ++;
            chars += word.length();
            avg = (double)chars / (double)words;
            System.out.println("Word count: " + words);
            System.out.println("Average length: " + avg);
        }
    }
}

Does it make any difference if BufferedReader is not used for single words. After I posted the orginal thread I contined working on this code and I used the if statement after the while like this...

 while (!word.equals("*")) 
      {
          word =  Dialog.request("enter next word");

            if (word.equals("*"))
           {
             break;
           } 

          count++;

           numberOfCharacters = numberOfCharacters + word.length();
           System.out.println(df.format(numberOfCharacters));
     }

but after seeing your code it makes sense. But what is the difference in what you provided and the I have just done?

Thanks sergb

It looks like there aren't many differences anymore. The code in your last post seems to be doing exactly what the code I posted was trying to do.

I used the BufferedReader for its readLine method because I was reading words from the stdin. If you have a different method of getting words--namely Dialog.request() )--then you don't need the BufferedReader at all.

It looks like you had it figured out before I posted the code.

thanks sergb, this has been solved. I will rate you if I am allowed...there is no function to rate you
