Help with a runtime error

Question

hey guys im getting a runtime error that i can't figure out.
this is my code
import java.io.*;
public class InputOutput
     public static void main(String[] args) throws IOException
          int charCount=0,
               wordCount=0,
               nonCharCount=0,
               lineCount=0;
          BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
          String fileName,outputFile, line;
          do
               System.out.println("Enter input file name.");
               fileName = input.readLine();
               System.out.println("Enter output file name.");
               outputFile = input.readLine();
               char [] charArray = new char [26];
               charArray[0] = 'a';
               for (int i=1; i<charArray.length; i++)
                    charArray[i] += 'a' + i;
               int [] countArray = new int [26];
               try
                    BufferedReader inputFile = new BufferedReader(new FileReader(fileName),1);
                    PrintWriter output = new PrintWriter(new FileWriter(outputFile));
                    line = inputFile.readLine();
                    while(line!=null)
                         String word = new String();
                         char ch;
                         for(int i=1; i<=line.length(); i++)
                              line = line.toLowerCase();
                              ch = line.charAt(i);
                              charCount++;
                              if(ch>='a' && ch<='z')
                                   word +=ch;
                                   int index = (int)ch - (int)'a';
                                   countArray[index]++;
                              else
                                   nonCharCount++;
                                   if(word!= "")
                                        output.println(word);
                                        word = "";
                                        wordCount++;
                         line = inputFile.readLine();
                         lineCount++;
                    output.println("Total number of words: "+wordCount);
                    output.println("Total number of lines: "+lineCount);
                    output.println("Total number of characters: "+charCount);
                    output.println("Total number of non-letter characters: "+nonCharCount);
                    for(int i=0; i<charArray.length; i++)
                         output.println(charArray[i] + " " + countArray);
                    output.close();
                    System.exit(0);
                    catch(IOException e)
                         System.out.println(e + ", try again");
               while(true);
this is the error that i am getting
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 35
     at java.lang.String.charAt(String.java:460)
     at InputOutput.main(InputOutput.java:52)

Hi,
The error is at line 52. You are trying to index an array with an index that is greater than the size of the array.
