How to open the default webbrowser using java

Can someone point me in the right direction on how to open the default web browser and set the page to "www.example.com" thanks

java.awt.Desktop is the class you're looking for.

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"));
}

For me solution with Desktop.isDesktopSupported() doesn't work (windows 7 and ubuntu). Please try this to open browser from java code:

Windows:

Runtime rt = Runtime.getRuntime();
String url = "http://stackoverflow.com";
rt.exec("rundll32 url.dll,FileProtocolHandler " + url);

Mac

Runtime rt = Runtime.getRuntime();
String url = "http://stackoverflow.com";
rt.exec("open " + url);

Linux:

Runtime rt = Runtime.getRuntime();
String url = "http://stackoverflow.com";
String[] browsers = { "google-chrome", "firefox", "mozilla", "epiphany", "konqueror",
                                 "netscape", "opera", "links", "lynx" };
 
StringBuffer cmd = new StringBuffer();
for (int i = 0; i < browsers.length; i++)
    if(i == 0)
        cmd.append(String.format(    "%s \"%s\"", browsers[i], url));
    else
        cmd.append(String.format(" || %s \"%s\"", browsers[i], url)); 
    // If the first didn't work, try the next browser and so on

rt.exec(new String[] { "sh", "-c", cmd.toString() });

If you want to have multiplatform application, you need to add operation system checking(for example):

String os = System.getProperty("os.name").toLowerCase();

Windows:

os.indexOf("win") >= 0

Mac:

os.indexOf("mac") >= 0

Linux:

os.indexOf("nix") >=0 || os.indexOf("nux") >=0

Here is my code. It'll open given url in default browser (cross platform solution).

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

public class Browser {
    public static void main(String[] args) {
        String url = "http://www.google.com";

        if(Desktop.isDesktopSupported()){
            Desktop desktop = Desktop.getDesktop();
            try {
                desktop.browse(new URI(url));
            } catch (IOException | URISyntaxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }else{
            Runtime runtime = Runtime.getRuntime();
            try {
                runtime.exec("xdg-open " + url);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}
