Hi

I placed BookDemo.java in c:\BookPack,
then I compile this file, it created two .class file

Next, I want to create the package. I go to the directory above BookPack, and issue this command:

C:\> package BookPack

The message shown as:

'package' is not recognized as an internal or external command, operable program or batch file.



Thanks

====================================================================

package BookPack;

class Book{
private String title;
private String author;
private int pubDate;

Book(String t, String a, int d){
title = t;
author = a;
pubDate = d;
}

void show(){
System.out.println(title);
System.out.println(author);
System.out.println(pubDate);
System.out.println();
}
}

class BookDemo{
public static void main(String[] args){
Book books[] = new Book[5];
books[0] = new Book("Java Beginners Guide", "Schildt", 2001);
books[1] = new Book("Java 2 Programmer Reference", "Schildt", 2002);
books[2] = new Book("HTML Programmer Reference", "Powell and Whitworth", 1998);
books[3] = new Book("Red Storm Rising", "Clancy", 1986);
books[4] = new Book("On the Road", "Kerouac", 1995);
}
}

There's no command package. If you want to create a package, you need to create a directory called BookPack in your case and then put your source code there. Then compile it using the normal javac.

I have created directory BookPack and place BookDemo.java in it.

Now, if I did this:

C:\BookPack> java BookPack.BookDemo

I will get:

Exception in thread :"main" java.lang.NoClassDefFoundError:BookPack/BookDemo

go one directory up, and execute the same command.

it should be

Welcome to the Ranch!

Please UseCodeTags when you post source code, so that your code is formatted nicely with line numbers. I added the code tags in your post above for you.

In which line do you get the error message? Please copy and paste the exact error message here.
 
It is sorta covered in the JavaRanch Style Guide.
