Java NIO file path issue

Question

I used the following code to get the path

Path errorFilePath = FileSystems.getDefault().getPath(errorFile);

When I try to move

Answer 1

To make it work on both Windows and Linux\OS X consider doing this:

String osAppropriatePath = System.getProperty( "os.name" ).contains( "indow" ) ? filePath.substring(1) : filePath;

If you want to worry about performance I'd store System.getProperty( "os.name" ).contains( "indow" ) as a constant like

private static final boolean IS_WINDOWS = System.getProperty( "os.name" ).contains( "indow" );

and then use:

String osAppropriatePath = IS_WINDOWS ? filePath.substring(1) : filePath;

Depending on how are you going to use the Path object, you may be able to avoid using Path at all:

// works with normal files but on a deployed JAR gives "java.nio.file.InvalidPathException: Illegal char <:> "
URL urlIcon = MyGui.class.getResource("myIcon.png");
Path pathIcon = new File(urlIcon.getPath()).toPath();
byte bytesIcon[] = Files.readAllBytes(pathIcon);


// works with normal files and with files inside JAR:
InputStream in = MyGui.class.getClassLoader().getResourceAsStream("myIcon.png");
byte bytesIcon[] = new byte[5000];
in.read(bytesIcon);
