Use the Desktop#browse(URI) method. It opens a URI in the user's default browser.

使用Desktop＃browse（URI）方法。它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;
}

#2

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

#3

try {
    Desktop.getDesktop().browse(new URL("http://www.google.com").toURI());
} catch (Exception e) {}

note: you have to include necessary imports from java.net

注意：您必须从java.net中包含必要的导入

A solution without the Desktop environment is BrowserLauncher2. This solution is more general as on Linux, Desktop is not always available.

没有桌面环境的解决方案是BrowserLauncher2。这个解决方案比Linux更通用，桌面并不总是可用。
