A solution without the Desktop environment is <a href="https://github.com/rajing/browserlauncher2" rel="nofollow noreferrer">BrowserLauncher2</a>. This solution is more general as on Linux, Desktop is not always available.

I know that this is an old question but sometimes the <code>Desktop.getDesktop()</code> produces an unexpected crash like in Ubuntu 18.04. Therefore, I have to re-write my code like this: 

<pre><code>public static void openURL(String domain)
{
 String url = "https://" + domain;
 Runtime rt = Runtime.getRuntime();
 try {
 if (MUtils.isWindows()) {
 rt.exec("rundll32 url.dll,FileProtocolHandler " + url).waitFor();
 Debug.log("Browser: " + url);
 } else if (MUtils.isMac()) {
 String[] cmd = {"open", url};
 rt.exec(cmd).waitFor();
 Debug.log("Browser: " + url);
 } else if (MUtils.isUnix()) {
 String[] cmd = {"xdg-open", url};
 rt.exec(cmd).waitFor();
 Debug.log("Browser: " + url);
 } else {
 try {
 throw new IllegalStateException();
 } catch (IllegalStateException e1) {
 MUtils.alertMessage(Lang.get("desktop.not.supported"), MainPn.getMainPn());
 e1.printStackTrace();
 }
 }
 } catch (IOException | InterruptedException e) {
 e.printStackTrace();
 }
}

public static boolean isWindows()
{
 return OS.contains("win");
}

public static boolean isMac()
{
 return OS.contains("mac");
}

public static boolean isUnix()
{
 return OS.contains("nix") || OS.contains("nux") || OS.indexOf("aix") &gt; 0;
}
</code></pre>

Then we can call this helper from the instance:

<pre><code>button.addActionListener(new ActionListener() {
 public void actionPerformed(ActionEvent e) {
 MUtils.openURL("www.google.com"); // just what is the 'open' method?
 }
});
</code></pre>

How can I open a link in default browser with a button click, along the lines of

<pre><code>button.addActionListener(new ActionListener() {
 public void actionPerformed(ActionEvent e) {
 open("www.google.com"); // just what is the 'open' method?
 }
});
</code></pre>

?

Open a link in browser with java button?

Linux

如何通过单击按钮在默认浏览器中打开链接，如下所示button.addActionListener(new ActionListener() {    public void actionPerformed(ActionEvent e) {        open("www.google.com"); // just what is the 'open' method?    }});
