In this tutorial, we will see “How to convert File to URL and vice versa in Java ?” While converting File to URL, we are first converting File to a URI and then URI to a URL. Similarly, while converting URL to a File, we convert URL to URI first and then URI to a File.
Convert File to URL and vice versa in Java...!!! Share on X
Example 1. Convert File to URL
import java.io.File;
import java.net.MalformedURLException;
import java.net.URI;
import java.net.URL;
public class FileToUrl_Example {
public static void main(String[] args) throws MalformedURLException {
File file;
URI uri;
URL url;
file = new File("/Users/d33p4k/Documents/Techndeck/JavaPractice/InputString");
if (file.exists() && file.isFile()) {
System.out.println("PATH: \n" + file.getPath());
// Convert file to a URI
uri = file.toURI();
System.out.println("\nURI: \n" + uri.toString());
// Convert URI to a URL
url = uri.toURL();
System.out.println("\nURL: \n" + url.toString());
} else {
System.out.println("File doesn't exist.");
}
}
}
Output:
PATH: /Users/d33p4k/Documents/Techndeck/JavaPractice/InputString URI: file:/Users/d33p4k/Documents/Techndeck/JavaPractice/InputString URL: file:/Users/d33p4k/Documents/Techndeck/JavaPractice/InputString
Example 2. Convert URL to File
import java.io.File;
import java.net.URI;
import java.net.URL;
public class UrlToFile_Example {
public static void main(String[] args) {
File file;
URI uri;
URL url;
try {
url = new URL("file:/Users/d33p4k/Documents/Techndeck/JavaPractice/InputString");
System.out.println("URL: \n" + url.toString());
//Convert URL to a URI
uri = url.toURI();
System.out.println("\nURI: \n" + uri.toString());
//Convert URI to a File
file = new File(uri.getPath());
System.out.println("\nPATH: \n" + file.getAbsolutePath());
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
Output:
URL: file:/Users/d33p4k/Documents/Techndeck/JavaPractice/InputString URI: file:/Users/d33p4k/Documents/Techndeck/JavaPractice/InputString PATH: /Users/d33p4k/Documents/Techndeck/JavaPractice/InputString
