如何在默认浏览器中打开链接，单击按钮，沿着

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

?

答案 1

使用桌面 #browse（URI）方法。它将在用户的默认浏览器中打开一个 URI。

public static boolean openWebpage(URI uri) {
    Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
    if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE)) {
        try {
            desktop.browse(uri);
            return true;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    return false;
}

public static boolean openWebpage(URL url) {
    try {
        return openWebpage(url.toURI());
    } catch (URISyntaxException e) {
        e.printStackTrace();
    }
    return false;
}

答案 2

public static void openWebpage(String urlString) {
    try {
        Desktop.getDesktop().browse(new URL(urlString).toURI());
    } catch (Exception e) {
        e.printStackTrace();
    }
}
