Having trouble with array

[ice22]

Hi im new to java and I am having a hard time trying to figure out why the input file is initialized into the array. When the array prints I simply get 26zeroes. Any help would be greatly appreciated.

Thank you.

import java.util.*;
import java.io.FileInputStream;
import java.io.*;

public class me
{
static final int ARRAY_SIZE=26;
static Scanner console=new Scanner(System.in);

public static void main(String[]args)
throws FileNotFoundException, IOException

{

int []list=new int[26];
int counter=0;
String s="ABCD";
char A=s.charAt(0);
int i=(int)A;


Scanner inputStream=new Scanner(new FileReader("MessageIn.txt"));

for(i=0;i<26;i++)
System.out.print(list[i]+"");
int maxIndex;
int largestList;


maxIndex=0;
for(i=1;i<26;i++)
if(list[maxIndex]<list[i])
maxIndex=i;

largestList=list[maxIndex];

}

}

As far as I can tell, you aren't putting anything in the array.

Code:

import java.io.*;
import java.util.*;

public class FillArray
{
    public static void main(String[] args) throws FileNotFoundException,
                                                  IOException
    {
        String filePath = "fillArray.txt";
        // Count lines in file.
        Scanner scanner = new Scanner(new File(filePath));
        int lineCount = 0;
        while(scanner.hasNext()) {
            scanner.nextLine();
            lineCount++;
        }
        scanner.close();
        System.out.println(filePath + " has " + lineCount + " lines");

        // Initialize and fill an array with file data.
        int[] list = new int[lineCount];
        Scanner reader = new Scanner(new FileReader(filePath));
        for(int i = 0; i < list.length; i++) {
            String line = reader.nextLine();
            list[i] = Integer.parseInt(line);
        }
        reader.close();
        System.out.println("original list = " + Arrays.toString(list));

        // Sort the array of ints from high to low value.
        int maxIndex;
        int largestList = -Integer.MAX_VALUE;
        for(int i = 0; i < list.length; i++) {
            largestList = list[i];
            maxIndex = i;
            for(int j = i+1; j < list.length; j++) {
                if(list[j] > largestList) {
                    maxIndex = j;
                    largestList = list[j];
                }
            }
            if(maxIndex != i) {
                int temp = list[i];
                list[i] = largestList;
                list[maxIndex] = temp;
            }
        }
        System.out.println("sorted list   = " + Arrays.toString(list));
    }
}

Thank you so much. You have no idea how helpful you have been. the book I am using in class is nowhere near as good as this in showing how to do this. I doesnt even explain how to initialize an array from a file.

Thank you again
