Compilation error - "cannot resolve symbol"

[Philip Steel]

Hi there

I have made a package called com.wrox.library and compiled the following
class successfully:

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;
  }

}


When I try and compile the following class (part of the same package) which
inherits Book, I get the following error:
com\wrox\library\ChildrenBook.java:3: cannot resolve symbol
symbol : class Book
location: class com.wrox.library.ChildrenBook
public class ChildrenBook extends Book {
                                                   ^
1 error

Here's the code:

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);
  }
}
