函数题:Implement Library
我们需要构建代表每个图书馆的类,并管理书籍的集合。所有图书馆都有同样的时间:每天上午9点至下午5点。但是,它们具有不同的地址和图书藏书(即,一系列的图书对象)。
创建一个名为Library的类。复制并粘贴下面的程序框架。在此我们提供了一种创建两个图书馆的主方法,然后对书籍执行一些操作。但是,缺少所有方法和成员变量。你需要定义和实现缺失的方法。
阅读主方法,查看编译错误以找出所丢失的方法。注意有一些方法需要静态方法,而某些则需要是实例方法。比较Strings对象时要小心。使用string1.equals(string2)比较内容string1和string2。
不允许修改main方法。运行此程序时,输出应类似于以下内容:
Library hours:
Libraries are open daily from 9am to 5pm.
Library addresses:
10 Main St.
228 Liberty St.
Borrowing The Lord of the Rings:
You successfully borrowed The Lord of the Rings
Sorry, this book is already borrowed.
Sorry, this book is not in our catalog.
Books available in the first library:
The Da Vinci Code
Le Petit Prince
A Tale of Two Cities
Books available in the second library:
No book in catalog
Returning The Lord of the Rings:
You successfully returned The Lord of the Rings
Books available in the first library:
The Da Vinci Code
Le Petit Prince
A Tale of Two Cities
The Lord of the Rings
### Library类的设计:
根据给出的裁判测试程序,设计完整的Library类。
class Library {
// Add the missing implementation to this class
}
### 裁判测试程序样例:
public class Main {
public static void main(String[] args) {
// Create two libraries
Library firstLibrary = new Library("10 Main St.");
Library secondLibrary = new Library("228 Liberty St.");
// Add four books to the first library
firstLibrary.addBook(new Book("The Da Vinci Code"));
firstLibrary.addBook(new Book("Le Petit Prince"));
firstLibrary.addBook(new Book("A Tale of Two Cities"));
firstLibrary.addBook(new Book("The Lord of the Rings"));
// Print opening hours and the addresses
System.out.println("Library hours:");
Library.printOpeningHours();
System.out.println();
System.out.println("Library addresses:");
firstLibrary.printAddress();
secondLibrary.printAddress();
System.out.println();
// Try to borrow The Lords of the Rings from both libraries
System.out.println("Borrowing The Lord of the Rings:");
firstLibrary.borrowBook("The Lord of the Rings");
firstLibrary.borrowBook("The Lord of the Rings");
secondLibrary.borrowBook("The Lord of the Rings");
System.out.println();
// Print the titles of all available books from both libraries
System.out.println("Books available in the first library:");
firstLibrary.printAvailableBooks();
System.out.println();
System.out.println("Books available in the second library:");
secondLibrary.printAvailableBooks();
System.out.println();
// Return The Lords of the Rings to the first library
System.out.println("Returning The Lord of the Rings:");
firstLibrary.returnBook("The Lord of the Rings");
System.out.println();
// Print the titles of available from the first library
System.out.println("Books available in the first library:");
firstLibrary.printAvailableBooks();
}
}
