How to Open URLs in the Default Web Browser with Java?

Launching URLs in the Default Web Browser with Java

Opening the default web browser and directing it to a specific page is a common requirement in many Java applications. Here's how to accomplish this using the java.awt.Desktop class:

Desktop is a native class that provides access to the native desktop environment. It has methods to manipulate files and directories, and to browse URLs in the default web browser.

To open a URL in the default web browser, you can use the browse() method of the Desktop class. This method takes a URI object as an argument, which represents the URL you want to open.

Here's an example code snippet that demonstrates how to use the Desktop class to open the URL "www.example.com" in the default web browser:

<code class="java">import java.awt.Desktop;
import java.net.URI;

// ...

if (Desktop.isDesktopSupported() && Desktop.getDesktop().isSupported(Desktop.Action.BROWSE)) {
    Desktop.getDesktop().browse(new URI("http://www.example.com"));
}</code>

First, we check if the Desktop class is supported on the current platform. If it's not supported, we cannot open the URL in the web browser.

Next, we check if the Desktop instance supports the BROWSE action. This action indicates that we want to open a URL in the default web browser.

Finally, if both checks are successful, we call the browse() method with the desired URI. This opens the specified URL in the default web browser.
