This applet shows that there are three radio buttons to change the label content. Here are a few notes: 1. To set up a single-choice button, you need the buttongroup class to define a group of related single-choice buttons.2. Each single-choice button must be added to the button group, and each button must be added to the Panel independently.3. The buttongroup object is not an organizational object and the created container is displayed. This is only a method for defining the button groups that

Because you don't have to include a local browser in your application, the download speed is faster. The browser component API allows you to access several browser events and control history (forward, backward, and refresh ). The API version that will be revised in the future is expected to provide more access to browsers and arbitrary documents. It is
