    Default Filelettercounter- 'character not found'

    No matter what character I use, I keep getting 'character not found' when I try to use the code to search for it in a txt file.

    import java.util.Scanner;//needed for Scanner Class
    import java.io.*;//needed for input and output
    public class FileLetterCounter
         public static void main(String[] args)
                 throws IOException //begin main function
             int count =0;
             String filename;
             String str;
             char character;
             Scanner keyboard = new Scanner(System.in);
             System.out.println("Enter a file name ");
             filename = keyboard.nextLine();
             System.out.println("Enter a character ");
             str = keyboard.nextLine();
             character = str.charAt(0);
             File file=new File(filename);
             Scanner inputFile=new Scanner(file);
                 String line=inputFile.nextLine();
                 int len=line.length();
                 for(int i=0;i<len;i++)
                     if (line.charAt(i) == character)
             if(count <= 0)
             System.out.println("Character not found in the file");
                 System.out.println("Number of times character" +count+" in file");

    Default Re: Filelettercounter- 'character not found'

    System.out.println("Character not found in the file")
    Is this the statement that prints the message you see?

    Try debugging the code by adding a println statement that prints out every line as it is read from the file so you can see what the computer sees. Also print the the value of character.
    If you don't understand my answer, don't ignore it, ask a question.
