How To Open A Link In Browser By Using JButton In Java

While working on any Java project, sometimes you want to add a button that can open a specific URL on browser of the computer. You can add any link like social media, blog, website, forum, etc. This can be easily done in Java with the following -

1. Add the following libraries at the starting of your project.

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

2. Now add a JButton by which you want to open URL on browser.

JButton gitbt = new JButton("Github");

gitbt.setBounds(5,150, 190,40);

3. Add a action listner to that button.

gitbt.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        
        }
});

4. Now use this main code inside that action listner which actually opens the URL.

if (Desktop.isDesktopSupported()) {

    {
        Desktop dsktp = Desktop.getDesktop();


        try {
            desk.browse(new URI("https://pvdocs.blogspot.com/"));

        } catch (IOException ex) {
            throw new RuntimeException(ex);
        } catch (URISyntaxException ex) {
            throw new RuntimeException(ex);
        }
    }
}

Explanation of above code - 

In the starting, the code will check if the operating system is supported or not. Supported operating systems are - Linux, Windows, MacOS. 

Then, it will create a new instance of Desktop class and store it in the dsktp.

After that, there is try-catch block. It will try to open the URL and if any exception is thrown, it will rethrow it as RuntimeException.
