I've got an assessment where I need to create 3 classes. In one of the classes I need to have a constructor with a parameter of String type. It needs to allow me to create a new object (pack

of crisps) in which I am supposed to state the flavour of it. Whenever I try to create the object I get the textbox where I can type in the flavour of crisps but when I press ok I get the error (e.g. ) Cannot find symbol - variable bbq. I had a similar example before which took int type and it worked fine. When I compare my code with other - working examples - I really can't find what I am doing wrong. I would appreciate if someone could advise. public class PackOfCrisps { private String flavour; private int numOfCrisps; private boolean open; /** * Constructor for a single pack of crisps. */ public PackOfCrisps(String newFlavour) { flavour = newFlavour; numOfCrisps = 10; open = true; } /** * Return whether the packet is empty. */ public boolean isEmpty() { if (numOfCrisps == 0) { return true; } else return false; } /** * Return whether the packet is closed. */ public boolean isClosed() { return open; } /** * Change the boolean value of 'open' variable. */ public void open() { open = !open; } /** * Return the flavo

How ya doin?"); scc.p("Connected1 "); scc.p("Connected2 "); String a=scc.is; double b=scc.id; int c=scc.ii; scc.pl (a); scc.pl (b); scc.pl (c); } } and it gives me the following Error: "cannot find symbol- variable is What am I doing wrong? How can i fix this? Thanks in ahead! * Edit: Thank you so much for the answer! so i fixed it, and ran into another problem... I can not print out b or c because the print i wrote requires a String, and b and c can only be double and int, so that won't work. is there any way of changing the print (scc.p and scc.pr) so it will be able to recieve any kind of parameter? thanks! java variables input find symbol share|improve this question edited Nov 28 '12 at 5:04 asked Nov 27 '12 at 18:48 user1857509 613 () is missing. double b=scc.id; should be double b=scc.id();. –Eng.Fouad Nov 27 '12 at 18:51 is, id and ii are methods, not variables. –Lion Nov 27 '12 at 18:51 1 These comments should really be answers.

The question I've been set is: http://gtaforums.com/topic/738325-bluej-error/ Add two accessor methods to the class - getAuthor and getTitle - that return the author and title fields as their respective results. Test your class by creating some instances and calling the methods. Every time I try to create a new book I get a cannot find symbol error. e.g. If I try to make a book with error cannot "john" as the author and "beingjohn" as the title I get this: Error: cannot find symbol - variable john It's probably something really stupid that I'm not seeing haha. I haven't been doing this long at all so I'm still not too confident with programming. I'm using BlueJ software by the way. I've got this so far: /** * A class that maintains information on a book. * This might form part of a error cannot find larger application such * as a library system, for instance. * * @author (Peter Moncrieff.) * @version (17th January 2009.) */ class Book { private String author; private String title; /** * Set the author and title fields when this object * is constructed. */ public Book(String bookAuthor, String bookTitle) { author = bookAuthor; title = bookTitle; } /** * Accesses the author */ public String getbookAuthor() { return author; } /** * Accesses the title */ public String getbookTitle() { return title; } } Thanks.

Book book = new Book(john, beingJohn); // or like this...? Book book = new Book("John", "Being John"); The 2nd one is what you're looking for I believe. Strings are always enclosed in quotes, unless they are variables...like this next one. String john = "John"; String beingJohn = "Being John"; Book book = new Book(john, beingJohn); That one works equally well. Was This Post Helpful? 1 Back to top MultiQuote

(after a 1 minute briefing on bluej)Make sure you have a constructor and it is the same name as the class. It sounds like bluej gives you a base framework when you start a project. I'm willing to bet that it is someth
