Using javafx how do i get my datasetbook to run with the following? book: public class book { private string author; private string title; private int pages; public book(string auth, string titl, int pag) { author = auth; title = titl; pages = pag; } @override public string tostring() { return "book [author=" + author + ", title=" + title + ", pages=" + pages + "]"; } public string getauthor() { return author; } public string gettitle() { return title; } public int getpages() { return pages; } @override public boolean equals(object obj) { if (this == obj) return true; if (obj == null) return false; if (getclass() ! = obj. return false; book other = (book) obj; if (author == null) { if (other. author ! = null) return false; } else if (! author. equals(other. author)) return false; if (pages ! = other. pages) return false; if (title == null) { if (other. title ! = null) return false; } else if (! title. equals(other. title)) return false; return true; }}datasetbook: import java. util. arraylist; import java. util. arrays; /*** a simple store for book objects.** @author student**/public class datasetbook extends arraylist { /** * default constructor */ public datasetbook() { } /** * add a book to the store * * @param objtoadd * * @return true if the element was added to the collection, false otherwise */ public boolean add(book objtoadd) { return super. add(objtoadd); } /** * the number of books currently in the store * * @return number of book objects */ public int size() { return super. size(); } /** * determine the book with the fewest pages * * @return null if the store is empty. the book with the fewest pages * otherwise. if more than one book has the fewest number of pages, * the first one is returned. */ public book getmin() { if (super. { return null; } book mele = super. get(0); for (int i = 1; i < super. size(); i++) { if (mele. getpages() > (super. get(i). { mele = super. get(i); } } return mele; } /** * determine the book with the most pages * * @return null if the store is empty. the book with the most pages * otherwise. if more than one book has the most number of pages, * the first one is returned. */ public book getmax() { if (super. { return null; } book mele = super. get(0); for (int i = 1; i < super. size(); i++) { if (mele. getpages() < (super. get(i). { mele = super. get(i); } } return mele; } /** * a string representation of the store. * * @return a string containing the number of books in the store, * the minimum book, the largest book, and * the contents of the entire store. */ @override public string tostring() { return "datasetbook [\n size()=" + size() + "\n getmin()=" + getmin() + " getmax()=" + getmax() + " books=\n" + arrays. tostring(super. + "]"; } }import javafx. application. application; import javafx. event. actionevent; import javafx. event. eventhandler; import javafx. geometry. pos; import javafx. scene. scene; import javafx. scene. control. button; import javafx. scene. control. label; import javafx. scene. control. textfield; import javafx. scene. layout. stackpane; import javafx. scene. layout. vbox; import javafx. scene. layout. hbox; import javafx. scene. layout. pane; import javafx. scene. layout. borderpane; import javafx. scene. paint. color; import javafx. scene. text. text; import javafx. stage. stage; public class handler extends application{ public void start(stage stage) { label author= new label("author"); //creating labels and textfields textfield textfield= new textfield(); label title= new label("title"); textfield textfield2= new textfield(); label pages= new label("pages"); textfield textfield3= new textfield(); button button= new button("make a new book"); //creating button button. setalignment(pos. top_right); hbox hb = new hbox(); hb.(author, textfield, title, textfield2, pages, textfield3, button); hb. setspacing(10); borderpane borderpane= new borderpane(); borderpane. settop(hb); borderpane. setalignment(hb, pos. top_center); scene scene= new scene(borderpane, 800, 500); stage. settitle("a simple book store"); stage. setscene(scene); stage. show(); }}
