implement the “back” feature in simple browser.with JAVAFX

Do not use the history that comes with the WebView / WebEngine. Use your own stack for that. The “back” operation requires that each web page (URL) that is accessed be stored in a stack (use the Stack class in the Java API for this). Then, when the user wants to go back, you basically need to pop the address of the last page accessed and go to it. As a first step, you need to create a stack and populate it as the user access each page. Note that there are many ways of accessing a page: by typing an address in the textfield, by selecting a bookmark, by selecting the “go to home” option, or by clicking a hypertext link on the page currently being viewed. Each of these ways should end up storing the address of the page accessed, so choose the correct place to put such code. In order to confirm that this partial step works properly, you can print the content of the stack when closing the application (partial marks given for this). Then, you should implement the method that gets called when selecting “back” in the menu. This should pop the address of the last visited page, and get this page displayed. Be careful: if there are no such previous page, the program should just do nothing (not crash!). Also note that when running your application, do not try to use the “back” option too fast...give enough time for the address area to be updated with the address of the web page before hitting “back” again (or before moving to other pages).
