java - Printing from Arrays -


i having trouble printing references in string method. used array story 1 of constructors' parameters. in order me use tostring have include variables including reference includes parameters constructor. 

author au10 = new author("dan gheesling", 29);         mydate my10 = new mydate(2011);         books[9] = new book(au10, "big brother - survival guide", my10, 32.99);          (book book : books) {              system.out.println(book);            system.out.println();        }  public book(author author, string title, mydate publishing, double price)   {          this.author = author;         this.title = title;         this.publishing = publishing;         }  @override public string tostring()    {       return  author.class.togenericstring() + "\n" +             "title: " + this.title + "\n" +              "publication date: " + this.publishing + "\n" +             "price: " + this.price;     }

instead of overriding tostring() method can directly print result in enhanced loop this:

for (book book : books) {

       system.out.println("title: " + book.title + "\n" +          "publication date: " + book.publishing + "\n" +         "price: " + book.price;);        system.out.println();    }

or can try using following code in yout tostring method

public string tostring() {

//whatever name of variable in author class return  this.author.name + "\n" +           this.author.value + "\n" +          "title: " + this.title + "\n" +          "publication date: " + this.publishing + "\n" +         "price: " + this.price;

}
