How to run and print this code

Hi Ladies and Gentlemen

I have a problem to run this code. After typing javac Book.java It compiled without error. But, when i typed java Book and press enter to run the program, it shows Exception in thread "main" java.lang. Noclass Def Found error:Book I don't know what to press after writting java Book.

Here is the code

public class Book{

Book b = new Book();
public static void main (String[] args) {
System.out.prinln ("Your Book");
}
}

Please UseCodeTags.

I doubt that code compiled.

Sure it compiled without error. Or why do you think not? Well, I'm new to java. Ok. I wrote prinln in this forum instead of System.out.println("Your Book") ; But, it was correct on my computer and compiled.

In addition to using code tags it's helpful to PostRealCode.

Is the code in the default package? (In other words, no package keyword?)

Wait--you have SCJP 5.0?

Follow this procedure.
1. Create a dir in C drive as javaexample
2.set CLASSPATH as C:\javaexample in Environment Variable
3.run from command prompt C:\javaexample>javac Book.java
4. run from command prompt C:\javaexample>java Book

it will work

No, don't set up a classpath. It will do more harm than good. When you open the command prompt create a directory there and navigate thither with these or similar commands:

mkdir java
cd java
. . .

Put your Book.java file in that directory

. . .
javac Book.java
java Book

Now you have a "java" directory for your Java work.
