Question

I currently have the following code:

public class Count {

    public static void countChar() throws FileNotFoundException {
        Scanner scannerFile = null;

        try {
            scannerFile = new Scanner(new File("file"));
        } catch (FileNotFoundException e) {
        }

        int starNumber = 0; // number of *'s

        while (scannerFile.hasNext()) {
            String character = scannerFile.next();
            int index =0;
            char star = '*';
            while(index<character.length()) {

                if(character.charAt(index)==star){
                    starNumber++;
                }
                index++;
            }
            System.out.println(starNumber);
        }
    }

I’m trying to find out how many times a * occurs in a textfile. For example given a text file containing
Hi * My * name *

the method should return with 3

Currently what happens is with the above example the method would return:

0
1
1
2
2
3

Thanks in advance.

Everything in your method works fine, except that you print the count per line:

    while (scannerFile.hasNext()) {
        String character = scannerFile.next();
        int index =0;
        char star = '*';
        while(index<character.length()) {

            if(character.charAt(index)==star){
                starNumber++;
            }
            index++;
        }
        /* PRINTS the result for each line!!! */
        System.out.println(starNumber);
    }
