HELP please.. Very simple, but I can't do it...

Question

Hi,
How can i make and int be between 1 and 10? I'm using bluej. So I'm declaring the variable enjoyability as an int and then starting directly in the constructor like:
public class Book
private String author;
private String title;
private String cost;
private String numberOfPages;
private int enjoyability;
private String genre;
public Book(String author, String title, String cost, String numberOfPages, int enjoyability, String genre)
this.author = author;
this.title = title;
this.cost = cost;
this.numberOfPages = numberOfPages;
this.enjoyability = enjoyability;
this.genre = genre;
public String author()
return author;
public String title()
return title;
public String cost()
return cost;
public String numberOfPages()
return numberOfPages;
public int enjoyability()
return enjoyability;
public String genre()
return genre;
public void print()
System.out.println("\n############ LIBRARY ############");
System.out.println("----------Book Details-----------");
System.out.println(" Author: " + author() );
System.out.println(" Title: " + title() );
System.out.println(" Cost: " + cost() );
System.out.println(" Number of pages: " + numberOfPages() );
System.out.println(" Enjoyability: " + enjoyability() );
System.out.println(" Genre: " + genre() );
and then I have another class that stores the book I made and print it to the console:
public class Library
private ArrayList items;
* Constructor for objects of class Library
public Library()
items = new ArrayList();
public void addBook(Book newBook)
items.add(newBook);
public void alphaAdd()
public int numberOfItems()
return items.size();
public void print()
for(Iterator iter = items.iterator(); iter.hasNext(); ){
Book book = (Book)iter.next();
book.print();
System.out.println();
How can i limited it to be between 1 and 10?? Thanks

public class Book
private String author;
private String title;
private String cost;
private String numberOfPages;
private int enjoyability;
private String genre;
public Book(String author, String title, String cost, String numberOfPages, int enjoyability, String genre)
this.author = author;
this.title = title;
this.cost = cost;
this.numberOfPages = numberOfPages;
this.enjoyability = enjoyability;
this.genre = genre;
public String author()
return author;
public String title()
return title;
public String cost()
return cost;
public String numberOfPages()
return numberOfPages;
public int enjoyability()
return enjoyability;
public String genre()
return genre;
public void print()
System.out.println("\n############ LIBRARY ############");
System.out.println("----------Book Details-----------");
System.out.println(" Author: " + author() );
System.out.println(" Title: " + title() );
System.out.println(" Cost: " + cost() );
System.out.println(" Number of pages: " + numberOfPages() );
System.out.println(" Enjoyability: " + enjoyability() );
System.out.println(" Genre: " + genre() );
and then I have another class that stores the book I made and print it to the console:

public int numberOfItems()
return items.size();
public void print()
for(Iterator iter = items.iterator(); iter.hasNext(); ){
Book book = (Book)iter.next();
book.print();
System.out.println();
