Help with findWithinHorizon

[bijohnathan]

I am new to Java and currently learning it using the dummies book. I see findWithinHorizon(".", 0).charAt(0);
all the time, I understand that the "." is to find characters. What is the purpose of 0 and charAt(0) ?
if i run this code on the word "forget" it will come back with only one letter "f". However if i put it in a while loop it comesback with f, o, r, g, e, t All 6 letters, why is that ?? shouldnt this statement find the first letter and not all letters??

Yes, your last assumption is correct that it should find the first letter. Why? Because of the 0 you have used. The charAt(0) is IMHO overkill

The 0 means to take the fist character

. is a regular expression that means "1 char, whatever it is". So you're looking for the next char. So the returned string contains a single char.

To get the next word, use Scanner.next().
