URI path not absolute exception java(not android)

Question

I have the following piece of source code

import java.net.URI;
import java.net.URISyntaxException;

    File file = new File("pic.png");
    BufferedImage image = ImageIO.read(file);
    String string = "pic.png";
 //the code works fine until here
    URI path = new URI(string);
    File f = new File(path);
    ColorProcessor image = new ColorProcessor(ImageIO.read(f));

So the path that the File gets is correct. Image is buffered correctly also. Now my problem is that i'm getting the following exception

Exception in thread "main" java.lang.IllegalArgumentException: URI is not absolute
    at java.io.File.<init>(Unknown Source)

Why is my path not absolute?And how do i do it right?

If i change the path like this:

String string = "C:'\'Users'\'Jurgen'\'newFile'\'myProject'\'pic.png";

Also tried like this

String string = "C:/Users/Jurgen/newFile/myProject/pic.png";

Then i get a new exception

Exception in thread "main" java.lang.IllegalArgumentException: URI is not hierarchical
    at java.io.File.<init>(Unknown Source)

P.S. not working with android packages for uri

Thanks in advance=)

Solution

You are trying to create uniform resource identifier, but the name should follow the url conventions. This means, that it's necessary to provide a scheme (take a look here, to see all available schemes). So, in your case, you have to create the URI with string, like file:/pic.png or may be some other scheme.

As for your full path, it could be done like:

String string = "file:/C:/Users/Jurgen/newFile/myProject/pic.png";
