im trying to get the same heat index that prints int the program to write to a file. i have copied the procedure from another program that worked correctly. any help is appreciated.

import java.io.PrintWriter;
import java.io.IOException;
import java.util.Scanner;
import java.io.File;
public class HeatIndex
{
   public static void main(String [] args) throws IOException
   {

       Scanner inFile = new Scanner(new File("BIRMINGHAM AP,AL temp record test.txt"));

       double sumTemp = 0;
       double averageTemp = 0;
       double sumHumidity = 0;
       double averageHumidity = 0;
       double sumHeatIndex = 0;
       double averageHeatIndex = 0;
       int counter = 0;

       PrintWriter outFile = new PrintWriter (new File("writeFile.txt"));

       double bhamTemp[] = new double[12];
       for (int bhamTempIndex = 0; bhamTempIndex <= 11;)
        {

            bhamTemp[bhamTempIndex] = inFile.nextDouble();
            sumTemp += bhamTemp[bhamTempIndex];
            averageTemp = sumTemp/12;
            bhamTempIndex++;
        }    

        Scanner  inFile2 = new Scanner(new File("13876BIRMINGHAM AP,AL Humidity Record Test.txt"));
        double bhamHumidity[] = new double [12];
        for (int bhamHumidityIndex = 0; bhamHumidityIndex <= 11;)
        {
            bhamHumidity[bhamHumidityIndex] = inFile2.nextDouble();
            sumHumidity += bhamHumidity[bhamHumidityIndex];
            averageHumidity = sumHumidity/ 12;
            bhamHumidityIndex++;
        }

         double heatIndex[] = new double [12];
         for (int indexCounter = 0; indexCounter <= 11;)
         {

             heatIndex[indexCounter] = heatIndex[indexCounter] = -42.379 + (2.04901523 * bhamTemp[indexCounter]) + (10.14333127 * bhamHumidity[indexCounter]) - (.22475541 * bhamTemp[indexCounter] * bhamHumidity[indexCounter]) - (6.83783 * .001 * bhamTemp[indexCounter] * bhamTemp[indexCounter]) - (5.481717 * .01 * bhamHumidity[indexCounter] * bhamHumidity[indexCounter]) + (1.22874 * .001 * bhamTemp[indexCounter] * bhamTemp[indexCounter] * bhamHumidity[indexCounter]) + (8.5282 *  .0001 * bhamTemp[indexCounter] * bhamHumidity[indexCounter] * bhamHumidity[indexCounter]) - (1.99 *  .000001 * bhamTemp[indexCounter] * bhamTemp[indexCounter] * bhamHumidity[indexCounter] * bhamHumidity[indexCounter]);
             sumHeatIndex += heatIndex[indexCounter];
             averageHeatIndex = sumHeatIndex/12;
             outFile.println(heatIndex[indexCounter]);
            indexCounter++;

          }

Edited 3 Years Ago by mike_2000_17: Fixed formatting

Firstly, the start of the CODE block in posting your code here should be without '/' to display the formatted code correctly.

The way you set-up your Printwriter is without automatic flushing. You need to use flush() method after you write something into the file. Have a look on the documentation on how to set up automatic flushing.

are you just writing to the file once?

outFile.println(heatIndex[indexCounter]);
outFile.flush();
outFile.println(heatIndex[indexCounter]);
outFile.flush();

thank you for the help.
