Using scanner with a prompt and user input

Using scanner with a prompt and user input

I tried to do counting lines, words, character from user "inputted" file.
After this show counting and keep asking again.
If file doesn't exist print all data which have been counted during running.
Code:
public class KeepAskingApp {
private static int lines;
private static int words;
private static int chars;
public static void main(String[] args) {
boolean done = false;
//counters
int charsCount = 0, wordsCount = 0, linesCount = 0;
Scanner in = null;
Scanner scanner = null;
while (!done) {
try {
in = new Scanner(System.in);
System.out.print("Enter a (next) file name: ");
String input = in.nextLine();
scanner = new Scanner(new File(input));
while(scanner.hasNextLine()) {
lines += linesCount++;
Scanner lineScanner = new Scanner(scanner.nextLine());
lineScanner.useDelimiter(" ");
while(lineScanner.hasNext()) {
words += wordsCount++;
chars += charsCount += lineScanner.next().length();
}
System.out.printf("# of chars: %d\n# of words: %d\n# of
lines: ",
charsCount, wordsCount, charsCount);
lineScanner.close();
}
scanner.close();
in.close();
} catch (FileNotFoundException e) {
System.out.printf("All lines: %d\nAll words: %d\nAll chars:
%d\n",
lines, words, chars);
System.out.println("The end");
done = true;
}
}
}
}
But I can't understand why it always show output with no parameters:
All lines: 0
All words: 0
All chars: 0
The end
Why it omits all internal part.
It may be coz I'm using few scanners, but all look ok. Any suggestions?
