URI path not absolute exception java (not android)

Question

I have the following source code snippet

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));

Thus, the path that the file receives is correct. The image is buffered correctly. Now my problem is that I get 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 am I doing it right?

If I change the path as follows:

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

And I 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)

PS does not work with android packages for uri

Thanks in advance =)
