Replacing letters through StreamTokenizer

Question

Hi,
I am writing a program which reads from a text file, passes it into a StreamTokenizer, looks for a particular word and capitalises the first letter (in this case "apples" to "Apples"). It's all fine, except when the word I'm looking for appears in the middle of a sentence, in which case, it seems to ignore it completely. I'm probably doing something really stupid, but I'd appreciate it if anyone could help me!
Input file:
John likes apples. apples are healthy.
The apples John eats are red, sometimes green. Most
apples come from farms.
Current output file:
John likes apples. Apples are healthy.
The apples John eats are red, sometimes green. Most
apples come from farms.
What output file is supposed to be:
John likes Apples. Apples are healthy.
The Apples John eats are red, sometimes green. Most
Apples come from farms.
Code:
//Filename:FileReader.java
import java.io.*;
public class FileReader
     public static void main(final String[]Args) throws IOException, FileNotFoundException
          //declares and instantiates the array aFileNames
          String[] aFileNames = new String[3];
          //read in the input & output file names and places them into an array
          for(int tArgNames = 0; tArgNames < Args.length; tArgNames ++)
               aFileNames[tArgNames] = Args[tArgNames];
          //instantiates a buffered reader
          BufferedReader tTextIn = new BufferedReader(new FileReader(aFileNames[0]));
          //declares and instantiates a stream tokenizer
          StreamTokenizer tStreamTokens = new StreamTokenizer(tTextIn);
          //declares a print writer for output file
          PrintWriter tTextOut = null;
          //instantiates the print writer for output file
          tTextOut = new PrintWriter(new FileWriter(aFileNames[1]));
          //declares a print writer for log file
          PrintWriter tTextLog = null;
          //instantiates the print writer for log file
          tTextLog = new PrintWriter(new FileWriter(aFileNames[2]));
          //Writes name of files being opened to log file
          tTextLog.println("File being opened: " + aFileNames[0]);
          tTextLog.println("File being opened: " + aFileNames[1]);
          //Line counter variable
          int tWordCounter = 0;
          //Word counter variable set at -1 to account for eof
          int tLineCounter = -1;
          //Recognises punctuation
          tStreamTokens.wordChars('.', '.');
          tStreamTokens.wordChars(',', ',');
          tStreamTokens.wordChars('\'', '\'');
          tStreamTokens.eolIsSignificant(true);
          //while there are more lines of text in the file
          while(tStreamTokens.nextToken() != StreamTokenizer.TT_EOF)
               //if the stream token is a string
               if(tStreamTokens.ttype == StreamTokenizer.TT_WORD)
                    //and if the token value is "apples"
                    if(tStreamTokens.sval.equals("apples"))
                         //change the stream token to "Apples"
                         tStreamTokens.sval = ("Apples");
                         tTextLog.println("Word changed at Line " + tStreamTokens.lineno());
                    //increment the word counter
                    tWordCounter++;
               //if the end of the line has been reached, increment the line counter
               else if(tStreamTokens.ttype == StreamTokenizer.TT_EOL)
                    tStreamTokens.sval = ("");
                    tTextOut.println("");
                    tLineCounter ++;
                    tTextLog.print("End of line reached. Word Count: " + tWordCounter + " . ");
                    tTextLog.println("Line Count: " + tLineCounter);
               //writes the current token to the output file named in the command line
               tTextOut.print(tStreamTokens.sval + " ");
          //prints the values to the designated output file
          tTextOut.println("Name of input file: " + aFileNames[0]);
          tTextOut.println("Number of lines: " + tLineCounter);
          tTextOut.println("Number of words: " + tWordCounter);
          //prints the values to the command prompt
          System.out.println("Name of input file: " + aFileNames[0]);
          System.out.println("Number of lines: " + tLineCounter);
          System.out.println("Number of words: " + tWordCounter);
          //prints the values to the log file
          tTextLog.println("Total Number of Lines: " + tLineCounter);
          tTextLog.println("Total Number of Words: " + tWordCounter);
          //Writes name of files being closed to log file
          tTextLog.println("File being closed: " + aFileNames[0]);
          tTextLog.println("File being closed: " + aFileNames[1]);
          //Closes the files
          tTextIn.close();
          tTextOut.close();
          tTextLog.close();
}Apologies for the not-very-nice code. I'd be grateful for any help on this.

for one, you might want it to check for "apples."Thanks for your help! I thought I was already
checking, here:
//and if the token value is "apples"
     if(tStreamTokens.sval.equals("apples")) ///<--here
          //change the stream token to "Apples"
          tStreamTokens.sval = ("Apples");
tTextLog.println("Word changed at Line " +
+  tStreamTokens.lineno());
     }but I'll have to look into it some more.

maybe you should read the post again. you need to check for the period too, dork.
     if(tStreamTokens.sval.equals("apples")) {     
     //change the stream token to "Apples"
             tStreamTokens.sval = ("Apples");
          tTextLog.println("Word changed at Line " +  tStreamTokens.lineno());
     }should be something like
     if(tStreamTokens.sval.equals("apples")) {     
     //change the stream token to "Apples"
             tStreamTokens.sval = ("Apples");
          tTextLog.println("Word changed at Line " +  tStreamTokens.lineno());
        }else if(tStreamTokens.sval.equals("apples.")) {     
     //checking for "apples." also
             tStreamTokens.sval = ("Apples.");
          tTextLog.println("Word changed at Line " +  tStreamTokens.lineno());
