Thread: I can't get Relative paths to work with the code I'm using.

Hello, I have been working on this all day. I can't get Relative paths to work. I have created the class.dat file and I can't get java to recognize it. I am using Eclipse as an IDE. Was wondering if I could get Eclipse to recognize it. I tried with a .txt file as well and couldn't get that to work.

import java.io.*;
 
public class ReadBytes
{
	public static void main(String[] args)
	{
		try
		{
			FileInputStream file = new FileInputStream("class.dat");
			boolean eof = false;
			int count = 0;
			while(!eof)
			{
				int input = file.read();
				System.out.print(input + " ");
 
				if (input == -1)
					eof = true;
				else
					count++;
			}
			file.close();
			System.out.println("\nBytes read: " + count);
 
		}
		catch (IOException e)
		{
			System.out.println("Error -- " + e.toString());
		}
	}
}

I'm sorry, just a beginner, not sure exactly how to do that. How do I create a File object and then print its absolute path. I found the code from an old textbook call Java 2 in 21 days.

Would appreciate if you could break it down for me.

check the spelling.

Hi Norm

Here is my code:

import java.io.*;
 
public class ReadBytes
{
	public static void main(String[] args)
	{
 
		File afile = new File("C:/Users/scott/Desktop/Midterm Quiz/Midtermexam");
		System.out.println("an ID "+ afile.getAbsolutePath());
 
 
 
	}
}

I get the absolute path in the console back as C:\Users\scott\Desktop\Midterm Quiz\Midtermexam

How do I get the relative path?

Thanks

S
