char array terminates for loop at spaces

[theNewb]

Hey All,

My objective is to : Write a small program that asks the user to input the name of a good book that he or she has read recently, stores the input as elements of a character array rather than as a string, then counts the occurrences of the letter 'a' in the input.

My problem is that my program only works when there are no spaces in the title, if there is a space the program stops counting the letter a's after that point. It seems that the spaces are terminating my for loop. Why does that happen?

I've been googling, and picking at the program for hours now -- but I just can't figure this last part out.

Program below:

import java.util.Scanner;

public class GoodBook {

public static void main(String[] args)
{
Scanner in = new Scanner(System.in);

System.out.print("Enter the name of a good book you've read recently:");
String yourBook = in.next();
char bookArray [] = yourBook.toCharArray();

int lettersA = 0;
for (int index = 0; index < bookArray.length; index++) {
if ((bookArray[index] == 'a') || (bookArray[index] == 'A')) {
lettersA++;
}
}
System.out.println(lettersA);
}
}

Thanks in advance for any and all help.

I'm not vertain, but I think the scanner tokenises strings using spaces as delimiters,

try

 String inString = "";
String temp = "";
while(temp != NULL)
{
  inString = inString + tem[;
  temp = in.next();
}
 

then call the toArray on inString and continue as you did

The problem is the method used to read in the input.

Calling next() on Scanner does not give the whole line(Just the next word) but calling nextLine() reads the full line.
Just change the code to

 String yourBook = in.nextLine();

Good to know! Thank-you very much. :)
