    Default Whats wrong here??

    It keeps saying that the method must return a result of type int but I already made return the result.


    import java.util.Scanner;
    public class chap9 {

    public static void main (String[] args) {


    String message = "statement";

    char letter = 'a';

    int num = count(message,letter);

    }

    public static int count(String str, char a){



    Scanner input = new Scanner(System.in);


    System.out.println("Enter the string");


    str = input.nextLine();
    int length = str.length();

    for(int i =0; i<length; i++) {

    a= 'a';


    int occurence =0;

    char b = str.charAt(i);

    if( b==a){

    occurence++;
    }




    return occurence;

    }
    }

    }

    saying that the method must return a result of type int
    Please copy the full text of the error message and paste it here.

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    The unformatted code makes it hard to read and understand.
    If you don't understand my answer, don't ignore it, ask a question.

    The formatting needs to be fixed. Nested statements should be indented 3-4 spaces.
    All statements should not start in the first column.

    Make sure ALL possible exit points from the method have a return statement.
    With the poor formatting, the code is hard to read to see where the exit points are.
