File input in Java for Mac

Question

We're learning file input and output in my programming class right now, but I have a Macbook Pro. I understand how to do it and I can do it on Windows but I'm having trouble finding out how to do it exactly for a Mac. I just can't seem to figure out what to put in the quotes for the 'File Fred = new File(" "); What do I need to put in the quotes to have it work? I have the file in the HDD named "David".

import java.util.Scanner;
import java.io.*;

public class FileIO
{

public static void main(String[] args)
{

    File Fred = new File("David:\\mytext.txt");
    try
    {   

Answer 1

Don't use "/" or "\" at all -- use System.getProperty("file.separator"). This will give you the correct character on the current OS. There are system properties that will help you write good cross-platform code. Check out System.getProperties() in the javadocs.

For example, to create "file.txt" in your home directory:

File myFile = new File(System.getProperty("user.home"), "file.txt");

That will work on OS X, Windows, and Linux.
