Object and Classes error: cannot find symbol

[darkseeker]

Hi guys,
I'm working on my java assignment but I don't know what did I do wrong. I successfully compile the file Book.java but got the error cannot find symbol while compiling BookTest.java . Thank you very much for any help.

Here's my Book.java

package question_1;
    public class Book {
    private String title; // Title of the book
    private String author; // Author of book :
    private String isbn; // International Standard Book Number 0-13-213198-7
    private float cost; // Cost of the book in U.S. dollars
    public Book() {
    title = "UnKnown";
    author = "UnKnown";
    isbn = "UnKnown";
    cost = 0;
    }
    public Book(String _title, String _author, String _isbn, float _cost) {
    title = _title;
    author = _author;
    isbn = _isbn;
    cost = _cost;
    }
    public String getTitle() {
    return title;
    }
    public String getAuthor() {
    return author;
    }
    public String getIsbn() {
    return isbn;
    }
    public float getCost() {
    return cost;
    }
    public void setTitle(String _title) {
    title = _title;
    }
    public void setAuthor(String _author) {
    author = _author;
    }
    public void setIsbn(String _isbn) {
    isbn = _isbn;
    }
    public void setCost(float _cost) {
    cost = _cost;
    }
    public double convertUsToEuro() {
    double euroconverted = 0;
    euroconverted = .73 * cost;
    return euroconverted;
    }
    }

And here's my BookTest.java:

package question_1;

    import javax.swing.JFrame;
    import javax.swing.JOptionPane;
    import java.*;
    public class BookTest {
    public void test() {
    System.out.println("Begin test");
    Book book1 = new Book("Programing Java", "Sun System", "001", 86);
    Book book2 = new Book("Programing C#", "MS", "002", 89);
    /// print output for user
    JOptionPane.showMessageDialog(new JFrame(), "Book 1nTitle: " + book1.getTitle() + "nAuthor: " + book1.getAuthor() + "nISBN: " + book1.getIsbn() + "nCost in USD: " + book1.getCost() + "nCost in Euro: " + book1.convertUsToEuro());
    JOptionPane.showMessageDialog(new JFrame(), "Book 2nTitle: " + book2.getTitle() + "nAuthor: " + book2.getAuthor() + "nISBN: " + book2.getIsbn() + "nCost in USD: " + book2.getCost() + "nCost in Euro: " + book2.convertUsToEuro());
    }
    public static void main(String[] args) {
    BookTest obj = new BookTest();
    obj.test();
    }
    }

Errors:

    symbol : class Book
    location: class question_1.BookTest
    Book book1 = new Book("Programing Java", "Sun System", "001", 86);

hi Darkseeker,

Just remove your package name from both the classes, then it will work fine... :-)

Not really, putting classes in the default package is discouraged. The OP should rather move the files into a folder structure that matches their package declarations.

try importing the book class in the booktest.java file

import question_1.book;
