Re: Frustrated trying to Read File

Thanks to both of you for your replies.

Seems that the problem is I am using a prehistoric iBook (1999 version)
with OS 9.2 and Java 1.0.3. It's a mini dinosaur. The first issue
seems to be a problem in that it has no "import" that connects with
the entries FileInputStream and BufferedReader.

The second issue that the OS and Java will not "read" files even if I
use a simplified version that complies with no error which is shown
below:

import java.io.File;
import java.io.RandomAccessFile;
import java.io.IOException;

public class DemoRandomAccessFile {

    private static void doAccess() {

        try {
            File file = new File("NameAgeWeightFile.txt");
            RandomAccessFile raf = new RandomAccessFile(file, "rw");

            // Read a character
            byte ch = raf.readByte();
            System.out.println("Read first character of file: " +
(char)ch);

            // Now read the remaining portion of the line.
            // This will print out from where the file pointer is
located
            // (just after the '+' character) and print all remaining
characters
            // up until the end of line character.
            System.out.println("Read full line: " + raf.readLine());

            // Seek to the end of file
            raf.seek(file.length());

            // Append to the end of the file
            raf.write(0x0A);
            raf.writeBytes("This will complete the Demo");
            raf.close();

        } catch (IOException e) {
            System.out.println("IOException:");
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        doAccess();
    }

}

I need to figure out how to write a text file, one that this Java will
recognize: I have tried to do various forms of text files that are
saved using the name of "NameAgeWeightFile.txt (Simple text, Claris
Works, Appleworks etc ) then placing it in the same folder as the java
program, ..... , then use the above program to read it, But will not
read it :(.

Thanks again for your replies.
