Question

I’m trying to run this code that was supposed to be a cut and paste easy assignment from my teacher. However, after following the instructions I still get this error message:

“The specified file, ShapeData.txt was not found.”

which refers back to line 30.

I did cut and paste the file into the same folder as all the rest, so i’m not sure why I’m still getting the error. I also read about doing something in the command line, but not sure what it is I’m suppose to do.

(Oh, and this is not a homework assignment or anything that I can turn in for a grade. It is just something we can look at to get a better understanding.)

Here is my code, or at least the first couple of line anyway.

    public class Lab8 {

        private static Shape[] shapes; // An array to hold all the shape objects

        public static void main(String[] args) {
            DataReader reader = new DataReader("ShapeData.txt");// The reader is used to read data from a file


            // Display program information
            System.out.println("Ima Java Programmer");
            System.out.println("Shape Info");

            // Load data from the file
            if(reader.loadData("ShapeData.txt")) { // The filename is entered using a command-line argument
                shapes = reader.getShapeData(); // Store the arrays in the array

                // Display how many shapes were read from the file
                System.out.println("Successfully loaded " + shapes[0].getCount() + 
                                   " shapes from the selected data file!");
                displayMenu();
            }
        }

ShapeData.txt file must be in your working directory ,because here you not specified full path. working directory may be your java bin directory
