Question

When I run the following code, I get an error.

package practicing.io;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class JavaIO {
  public static void main(String[] args) throws IOException {
    FileInputStream in = null;
    FileOutputStream out = null;
    try {
        in = new FileInputStream("xanaduout.txt");
        out = new FileOutputStream("out.txt");
        int c;

        while ((c = in.read()) != -1) {
            out.write(c);
        }

    } finally {
        if (in != null) {
            in.close();
        }
        if (out != null) {
            out.close();
        }
    }
   }
}

This was taken right from Sun’s tutorial online. Please, tell me what’s wrong.

Answer 1

Does “xanaduout.txt” exist? In your current directory?

If not, you can always hard-code the path. But that’s not good practice 🙂

In any case, the error says exactly what’s happening: you’re trying to open a file … and the system can’t find it.
