Please change your displayed name to conform to our naming policy. In short, your name must be a first name and last name, separated by a space and not obviously fake. Now, about your question. No, but you can do something similar by calling AppletContext.showDocument() to load a new URL in the browser.
We ask that people use their real names because we want this place to be friendly to the newcomer and people seem to take the anynomity of the internet as a license to be short-tempered and insulting. Thanks for making the change and enjoy the Ranch.
