File.separator is portable, / is not, ugly or not always opt for the
more portable option.
For example, this code;
-------------------------------------------------------------------------------
import java.io.*;
public class FileSeparator
{
public static void main(String[] argv)
{
File temp = new File("temp/hello");
File temp2 = new File("temp\\hello");
File temp3 = new File("temp" + File.separator +
"hello");
temp.mkdirs();
System.out.println("dir " + temp +
" exists? "+ temp.exists());
System.out.println("dir " + temp2 +
" exists? " + temp2.exists());
System.out.println("dir " + temp3 +
" exists? " + temp3.exists());
}
}
-------------------------------------------------------------------------------
In Windows it outputs the following;
D:\**\file-separator>java FileSeparator
dir temp\hello exists? true
dir temp\hello exists? true
dir temp\hello exists? true
In Linux (Ubuntu) it outputs the following;
*...@ubuntu:~/**/file-separator$ java FileSeparator
dir temp/hello exists? true
dir temp\hello exists? false
dir temp/hello exists? true
