package chapter7.book;
import chapter7.book.librarian.Librarian;
import chapter7.book.reader.Reader;
public class BookTest 
{
	public static void main(String[] args) 
	{
		Reader reader = new Reader();
		System.out.println("以下处理订阅业务：");
		reader.subscribe(1);
		System.out.println("以下处理续借业务：");
		reader.continueLend(1);
		Librarian librarian = new Librarian();
		System.out.println("以下处理借书业务：");
		librarian.lendBook(1, "gzc");
		System.out.println("以下处理还书业务：");
		librarian.returnBook(1);
