Command Prompt: java file not found

Question

The file name is BookDemo.java and I compiled it like this: javac bookpack\BookDemo.java

This is my block of code:

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: A Beginner's Guide", 
                    "Schildt", 2011);  
books[1] = new Book("Java: The Complete Reference", 
                    "Schildt", 2011); 
books[2] = new Book("The Art of Java", 
                    "Schildt and Holmes", 2003); 
books[3] = new Book("Red Storm Rising", 
                     "Clancy", 1986);  
books[4] = new Book("On the Road", 
                    "Kerouac", 1955);  

for(int i=0; i < books.length; i++) books[i].show();  
   } 
}

The output is this:
javac: file not found:bookpack\BookDemo.java Usage: javac <options> <source files> use -help for a list of possible options

How can you fix this so that the code will execute? Thank you for your help!!!

Can you include the entire input and output? This sounds like it might be an issue with your PATH. — Pokechu22, Nov 21 '14 at 04:44

Post the command to run it. It might be that the name isn't fully qualified since it's in a package. Run it with java bookpack.BookDemo from the bookpack folder. — AtlasMeh-ed, Nov 21 '14 at 04:46

To run program you must try this command:

java bookpack.BookDemo

While running program, you need to specify the class containing main().

Make sure that cmd/termincal location is like e.g.

D:\
|
`+-your-folder(cmd here)
    |
    `+-bookpack

The compile never completed because javac could not successfully find your .java file. Try putting in the entire path to the file. For example, if the file is in C:\Users\James\bookpack\BookDemo.java, try running javac "C:\Users\James\bookpack\BookDemo.java".

After the compilation is complete, you would run it with java "C:\Users\James\bookpack\BookDemo".

When I do this, it says that "'javac' is recognized as an internal or external command, operable or batch files" – James Bond Nov 21 '14 at 05:06
Look into adding Java to your path environment variable. – RogueBaneling Nov 21 '14 at 05:09

I placed your code in file BookDemo.java inside directory C:\Java\new

And run commands below:

C:\Java\new>javac -version javac 1.7.0_40

C:\Java\new>javac -d . BookDemo.java

C:\Java\new>java bookpack.BookDemo Java: A Beginner's Guide Schildt 2011

Java: The Complete Reference Schildt 2011

The Art of Java Schildt and Holmes 2003

Red Storm Rising Clancy 1986

On the Road Kerouac 1955

C:\Java\new>

The command :

javac -version

for checking the javac already on your PATH .If it failure check the post here
