The first part of this recitation will be building a simple BrowserHistory class to handle the forward and back buttons (for use methods) of a simple web browser. Here is some starter code. Your job 13 to implement the code marked to be implemented class WebPaget String url; String content; WebPage (String url, string content) t this.ur1 = url ; this.content -content public void display) System.out.println("URL:url); System.out.println( "Content: " content + " "); /* Doubly Linked list Node/ class Historystate t This activity is licensed under CC BY-SA 4.0 license. 1/4 CSCI-UA 102, In-class Group Activity WebPage page; Historystate prev; Historystate next // Constructor to create a new state // next and prev is by default initialized as null Historystate (WebPage p) t page p; class BrowserHistory t Historystate current; WebPage errorPage BrowserHistory() f current-null; errorPage new WebPage(null, "404 not found"); / Implement needed methods here // 1. navigate /I 2. back 3. forward Here is the main class that will be used to test your code public class recitation3 t public static void main(Stringl] args) BrowserHistory history -new BrowserHistory: history.back().display); history.navigate("www.nyu.edu", "we love purple").display); history.navigate("www.google.com, search for stuff") display O history.navigate("www.yahoo.com", "did you get lost looking for google?").display() history.navigate("www.amazon.com* "buy stuff").display() history.forward().display ); history.back().display); history.back).display); history.navigate("www.facebook.com", "search for friends").display) history.forward().display ); history.back().display); history.back).display ); history.back).display); history.forward().display); This activity is licensed under CC BY.SA 40 license 2/4 CSCI-UA 102, In-class Group Activity history.forward).display); Your code must match this output: No valid current page!
