So I have pretty much completed (I think) my wc program in Java, that takes a filename from a user input (even multiple), and counts the lines, words, bytes (number of characters) from the file. There were 2 files provided for testing purposes, and they are in a .dat format, being readable from dos/linux command lines. Everything is working properly except for the count when there are \n or \r\n characters at the end of line. It will not count these. Please help?

that is the entire program, if anyone helping should need to see anything, however this is where I count the length of each string in a line (and I assumed that the eol characters would be part of this count, but they aren't.)
public static void countMultiple(String fileName, BufferedReader in) {
try {
String line;
String[] words;
int totalWords1 = 0;
int lines = 0;
int chars = 0;
while ((line = in.readLine()) != null) {
lines++;
currentLines = lines;
**chars += line.length();**
currentBytes = chars;
words = line.split(" ");
totalWords1 += countWords(line);
currentWords = totalWords1;
} // End of while loop.
totalLines += currentLines;
totalBytes += currentBytes;
totalWords += totalWords1;
} catch (Exception ex) {
ex.printStackTrace();
}
}
