Compile error by the Word extends

Question

Hi List
I'm a absolut newbie, so don't laugh if the the problem is not a really one.
I want to compile a file it's called ChildrenBook.java.
I always get the sam error after the prompt.
c:\temp\javac ChildrenBook.java
ChildrenBook.java:3: cannot resolve symbol
symbol : class Book
location : class com.wrox.library.ChildrenBook
public class ChildrenBook extends Book {
1error
(where there is a arrow under the B of Book)
the Code of Book.java and ChildrenBook.java are below
I don't know the failure. Is a special Classpath neccessary?
I hope you can help me?
package com.wrox.library;
public class Book {
private String title;
public String getTitle() {
return title;
public void setTitle(String title) {
this.title = title;
public Book() {
public Book(String title) {
this.title = title;
package com.wrox.library;
public class ChildrenBook extends Book {
private int minimumAge;
public int getMinimumAge() {
return minimumAge;
public void setMinimumAge(int a) {
minimumAge = a;
public String getType() {
return "CHILDREN";
public ChildrenBook() {
super();
public ChildrenBook(String title) {
super(title);
}

Answer 1

c:\temp\javac ChildrenBook.javaIn your c:\temp directory, try creating the directories com\wrox\library\ and put the two files in here. You would also need c:\temp on your classpath (in the DOS prompt type:
set CLASSPATH=c:\temp;%CLASSPATH%
