Scanner not working as intended(Java)

Question

Scanner m = new Scanner(new File("C:\\Map.txt));
System.out.println(m.next());

say the Map.txt has the line fgdfgdfgfgfdg in it.

when i try to use it, it prints the whole line instead of one token/letter at a time. How can I read only 1 letter?

P.S - I'm aware the file has to be in a try-catch block, I ommitted that here and I also tried using FileReader instead of File, same thing happens.

Why do you think it should read one token or letter at a time the way you have it? — Sotirios Delimanolis, Jun 16 '14 at 15:43

m.next() takes the whole word, that is every letter until the next whitespace. You can do something like this:

Scanner m = new Scanner(...);
System.out.println(m.next().charAt(0));

Edit: For reading one char at a time you would then store the word as a string and loop through the chars

Scanner m = new Scanner(...);
String word = m.next();

for (int i = 0; i < word.length(); i++) {
    System.out.println(word.charAt(i));
}

wouldn't that print the first letter of each word? – Alexandru Severin Jun 16 '14 at 15:46
Would only print first letter of the first word. I'll update answer. – Einar Jun 16 '14 at 15:47
