        }
        catch (MalformedURLException e) {
            System.out.println("Malformed URL: " + e.getMessage());
        }
        try {
        	// getting URI from url
            URI uri = url.toURI();
            System.out.println("URI from URL: " + uri);
        }

Output:

URL created: https://www.javatpoint.com/URL-class
URI from URL: https://www.javatpoint.com/URL-class

Example 2

import java.io.File;
import java.io.IOException;
import java.net.*;

public class URLtoURIExample2 {

	public static void main(String[] args) throws IOException, URISyntaxException {

		File file = new File("file name with spaces.txt");
		URL fileUrl = file.toURI().toURL();
		System.out.println("URL:" + fileUrl);
		//Changing url to uri
		URI fileUri = fileUrl.toURI();
		System.out.println("URI:" + fileUri);
		URL f = file.toURL();
		System.out.println("URL (no special character handling):" + f);
	}
}

Output:

URL:file:/D:/Advancejava/UrlClass/file%20name%20with%20spaces.txt
URI:file:/D:/Advancejava/UrlClass/file%20name%20with%20spaces.txt
URL (no special character handling):file:/D:/Advancejava/UrlClass/file name with spaces.txt
