How to open a non-default browser from a Java program, such as Tor?

Question

Java

There is a need to open not the default browser from the program code, but the Tor browser, but on the Internet I found only how to pass the URL to the browser, which is set as the default browser. Thanks in advance.

There are two ways:

String pathToTor = "D:\\Tor\\Tor Browser\\Browser\\firefox.exe"; //путь к браузеру 
        String link = "http:\\stackoverflow.com\\"; //ссылка
        String request = String.format("%s %s", pathToTor, link);
        Runtime runtime = Runtime.getRuntime();
        runtime.exec(request);

Use my class (drafted in haste):

public class BrowserOpener {

    private String os;
    private Runtime runtime;

    public BrowserOpener() {

        os = System.getProperty("os.name").toLowerCase();
        runtime = Runtime.getRuntime();
    }

    public void openLinkInBrowser(String url) {

        try {
            if (isWindows()) {
                runtime.exec("rundll32 url.dll,FileProtocolHandler " + url);
            } else if (isMac()) {
                runtime.exec("open " + url);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    private boolean isWindows() {
        return os.contains("win");
    }

    private boolean isMac() {
        return os.contains("mac");
    }


}

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

public class Main {

    public static void main(String[] args) throws IOException, URISyntaxException {

        BrowserOpener opener = new BrowserOpener();
        opener.openLinkInBrowser("http://stackoverflow.com/");


    }


}

• Absolute path not needed
  
• Offers a choice to the user
