File I/O: Reading from one file and writing to another (Java)

file, io, java

Solution

You need to figure out where it looks for the `"input"` file. When you just specify `"input"` it looks for the file in the current working directory. When working with an IDE, this directory may not be what you think it is.

Try the following:

System.out.println(new File("input").getAbsolutePath());

to see where it looks for the file.

Problem

I'm currently working on a lab in my cpe class and we have to create a simple program that scans in strings from a .txt file and prints them to a different .txt file. So far I have the basic program drawn out but my exception keeps getting throw though I have all the necessary files. Can anyone help me debug? ``` import java.io.*; import java.util.*; public class FileIO { public static void main(String args[]) { try { File input = new File("input"); File output = new File("output"); Scanner sc = new Scanner(input); PrintWriter printer = new PrintWriter(output); while(sc.hasNextLine()) { String s = sc.nextLine(); printer.write(s); } } catch(FileNotFoundException e) { System.err.println("File not found. Please scan in new file."); } } } ```
