"Inside the C++ Object Model" 是由 Stanley B. Lippman 所著的经典之作，深度探讨了C++对象模型的内部工作机制。这本书是对面向对象编程概念的深入剖析，特别针对那些已经拥有多年C++编程经验的读者设计，旨在解答关于构建式、解构式、虚函数、继承和多态等核心概念的疑问。 Lippman的著作深入探讨了C++对象模型的各个方面，包括： 1. Object Lessons：通过实际案例，学习如何理解和应用对象的基本原理，以及它们在程序中的作用。 2. The Semantics of Constructors：构造函数的语义，即创建对象时执行的操作，包括初始化过程和内存管理。 3. The Semantics of Data：数据成员的组织和访问，包括私有、公有和保护成员，以及访问控制的概念。 4. The Semantics of Functions：函数在对象中的角色，特别是静态成员函数和虚函数的实现机制。 5. Semantics of Construction, Destruction, and Copy：对象的生命周期管理，包括构造、析构和拷贝操作的内在逻辑。 6. Runtime Semantics：运行时的行为，涉及动态绑定、类型转换和虚函数的实际调用。 7. On the Cusp of the Object Model：探讨C++对象模型的边界，以及与其他编程范式（如过程化编程）的对比和融合。 书中还提到了多型（Polymorphism）这一强大特性，它是C++的核心组件之一，但其底层实现原理并不明显，本书提供了对其工作原理的洞察。阅读这本书有助于理解编译器如何处理这些高级特性，消除对C++语言深层次运作的疑惑。 对于希望进一步发展成为组件式软件开发者的人来说，《Inside the C++ Object Model》是一本不可或缺的参考书。它不仅是学习COM（Component Object Model）和CORBA（Common Object Request Broker Architecture）的基础，也为理解现代软件架构的组件化和模块化提供了关键的知识支持。 这本书不仅适合C++程序员提升对对象模型的理解，也是技术领导者和技术教育者的宝贵资源，帮助他们指导团队理解和优化C++项目的设计与实现。

帮我写出以下java代码：Add a class Bubble that extends Shape. The Bubble class has an instance variable called radius of type double that represents the radius of the bubble. The constructor of the Bubble class takes an x and a y as arguments, which represent the position of the new bubble. The radius of a new bubble is always 10 and never changes after that. The isVisible method indicates whether the bubble is currently visible inside a window of width w and height h (position (0, 0) is in the upper-left corner of the window). The bubble is considered visible if at least one pixel of the bubble is visible. Therefore a bubble might be visible even when its center is outside the window, as long as the edge of the bubble is still visible inside the window. The code of the isVisible method is a little bit complex, mostly because of the case where the center of the circle is just outside one of the corners of the window. So here is the code of the isVisible method, which you can directly copy-paste into your assignment: // Find the point (wx, wy) inside the window which is closest to the // center (x, y) of the circle. In other words, find the wx in the // interval [0, w - 1] which is closest to x, and find the wy in the // interval [0, h - 1] which is closest to y. // If the distance between (wx, wy) and (x, y) is less than the radius // of the circle (using Pythagoras's theorem) then at least part of // the circle is visible in the window. // Note: if the center of the circle is inside the window, then (wx, wy) // is the same as (x, y), and the distance is 0. public boolean isVisible(int w, int h) { double x = getX(); double y = getY(); double wx = (x < 0 ? 0 : (x > w - 1 ? w - 1 : x)); double wy = (y < 0 ? 0 : (y > h - 1 ? h - 1 : y)); double dx = wx - x; double dy = wy - y; return dx * dx + dy * dy <= radius * radius; } The isIn method indicates whether the point at coordinates (x, y) (which are the arguments of the method) is currently inside the bubble or not. The edge of the bubble counts as being inside of the bubble. HINT: use Pythagoras's theorem to compute the distance from the center of the bubble to the point (x, y). The draw method uses the graphics object g to draw the bubble. HINT: remember that the color of the graphics object g is changed in the draw method of the superclass of Bubble. Also add a testBubble method to test all your methods (including inherited methods, but excluding the isVisible method, which I provide, and excluding the draw method since it requires as argument a graphics object g that you

write java。Once you have checked that your methods readLine and readPosInt work correctly, remove all the code inside the main method of the CLI class so that the main method is empty again. In the rest of this question, use the readLine and readPosInt methods every time your program needs to read a string or an integer from the user. In the empty main method of the CLI class, create a single Library object with the name "hhh Library". The main method of the CLI class must then print a menu that allows the user of your system to do six different actions that involve the library object, and your program must then read an integer from the user that indicates which action must be performed by the program (see below for the details about each action). Use the readPosInt method to print the menu (give the string for the menu as the argument of readPosInt) and to read the integer typed by the user.

Write a Model class with the following UML specification: +----------------------------------------------+ | Model | +----------------------------------------------+ | - score: int | | - bubbles: ArrayList<IShape> | +----------------------------------------------+ | + Model() | | + getScore(): int | | + addBubble(int w, int h): void | | + moveAll(int dx, int dy): void | | + clearInvisibles(int w, int h): void | | + deleteBubblesAtPoint(int x, int y): void | | + drawAll(Graphics g): void | | + testModel(): void | +----------------------------------------------+ When a new model object is created, the score must be zero and the arraylist must be empty. The getScore method returns as result the current score for the game. The addBubble method adds a new bubble to the arraylist of bubbles. The position of the center of the new bubble is random but must be inside a window of width w and height h (the arguments of the addBubble method), like this: new Bubble((int)(w * Math.random()), (int)(h * Math.random())) The moveAll method moves the positions of all the bubbles in the arraylist of bubbles by the amount dx in the x direction and by the amount dy in the y direction. The clearInvisibles method takes as argument the width w and the height h of the window, and deletes from the arraylist of bubbles any bubble which is not visible in the window anymore. For each bubble which is deleted, the score decreases by 1.The deleteBubblesAtPoint method takes as argument the coordinates (x, y) of a point, and deletes from the arraylist of bubbles any bubble which contains this point (multiple bubbles might contain the point, because bubbles can overlap in the window). For each bubble which is deleted, the score increases by 1. The drawAll method draws all the bubbles in the arraylist of bub

Finally, the testModel method is a debugging method which creates a new Model object, adds five bubbles, moves them, clears the ones outside the window, deletes the ones at a certain point, and then ...

Create a HistoryPanel class that extends JPanel. The constructor of HistoryPanel takes as argument a model object of type Library, which you need to store in some private instance variable. Add to the HistoryPanel class two private methods called historyMax and historyMin that take an arraylist of integers as argument and return as result the maximum and minimum number in the arraylist, respectively (you can assume that the arraylist contains at least one number). Then add to the HistoryPanel class a private method called historyRange that takes an arraylist of integers as argument and returns as result the difference between the max and min of the integers in the arraylist, or returns as result 10 if the difference between the man and min of the integers in the arraylist is strictly less than 10. Override the protected void paintComponent(Graphics g) method inherited from JPanel, and, inside your new paintComponent method, draw graphically how the total number of books borrowed by all users of the library changes over time, as follows:
