there is an increasing need for autonomous systems that exhibit effective de

随着科技的快速发展，人们对具备高效的自主系统的需求不断增加。自主系统是指能够独立地执行任务、适应环境变化并作出决策的智能系统。

首先，自主系统能够提高生产效率和工作效率。传统的人工操作往往需要大量的时间和劳动力，而自主系统可以通过机器学习和人工智能技术，快速学习和适应环境，更高效地完成任务。这将大大减少人力成本，并提高生产效率。

其次，自主系统的应用可以降低人员风险和危险。在一些危险环境下，如火灾、核辐射或其他有害物质的存在下，使用自主系统可以保证人员的安全。自主系统可以承担一些危险和高风险的任务，减少人员暴露在危险环境中的时间和风险。

此外，自主系统的发展还可以改善交通运输和物流领域。无人驾驶汽车和自主无人机可以在交通拥堵、配送等方面提供更高的效率和准确性。这将减少交通事故的发生，并提高物流行业的效率。

另外，自主系统还能够改善医疗行业。自主机器人可以在手术过程中辅助医生，减少手术风险和提高手术效果。此外，自主系统还可以帮助老年人和残障人士进行生活上的辅助，提高他们的生活质量。

综上所述，由于其高效性、安全性和可靠性，自主系统的需求逐渐增加。各个领域都正在积极探索和应用自主系统，以满足人们在生产、生活和工作中的日益增长的需求。

Also create a ControllerMoreBook class that extends Controller.The moreBook method takes the name of a user and a number of books (as a string) as arguments. The moreBook method of the controller then transforms the number of books from a string to an integer (using the Integer.parseInt static method) and calls the moreBook method of the library to increase the number of books borrowed or lent by the user (depending on what kind of user it is) of a specific user, by the given argument. • If no exception occurs then the moreBook method of the controller returns the empty string. • If the moreBook method of the library throws an UnknownUserException then the moreBook method of the controller must catch this exception and return as result the error message from the exception object. • If the moreBook method of the library throws a NotALenderException then the moreBook method of the controller must catch this exception and return as result the error message from the exception object. • If the parseInt method of the Integer class throws a NumberFormatException (because the user typed something which is not an integer) then the moreBook method of the controller must catch this exception and return as result the error message from the exception object. Note: to keep things simple, it is allowed for a user of your system to increase the number of books of a user by a negative number, so there is no need to check for that. Modify the run method of the GUI class to add a ViewMoreBook view that uses a ControllerMoreBook controller and the same model as before (not a new model!) Do not delete the previous views. Run your GUI and check that you can correctly use the new view to increase the number of books for different users of your library (obviously your library must have some users in it to test this: see the last paragraph of Question 7). • Check that, when you increase a user’s book, the simple view is automatically correctly updated to show the new total number of borrowed books for all users of the library. • Also use the “get book” view to check that the user’s book value correctly changed. • Also check that increasing the book number of an unknown user correctly shows an error message.Also check that increasing the book of a user by a large negative number correctly shows an error message. Also check that trying to increase the book of a user by a number which is not an integer correctly shows an error message (do not worry about the content of the error message). 完成符合以上要求的java代码

修改 GUI 类的 run 方法：

public void run() {
    Library library = new Library();
    library.addUser(new Lender("Alice"));
    library.addUser(new Lender("Bob"));
    library.addUser(new Borrower("Charlie"));

    ControllerSimple simpleController = new ControllerSimple(library);
    ViewSimple simpleView = new ViewSimple(simpleController);
    simpleView.setVisible(true);

    ControllerGetBook getBookController = new ControllerGetBook(library);
    ViewGetBook getBookView = new ViewGetBook(getBookController);
    getBookView.setVisible(true);

    ControllerMoreBook moreBookController = new ControllerMoreBook(library);
    ViewMoreBook moreBookView = new ViewMoreBook(moreBookController);
    moreBookView.setVisible(true);
}

There is not enough space for this component. Try decreasing its width, or increasing the destination width.

As an AI language model, I cannot provide specific suggestions without additional context. However, here are some general tips:

- Check the size of the component and compare it to the available space in the layout.
- Consider reducing the padding or margin around the component to make it fit better.
- Try using a different layout or positioning the component in a different location.
- If possible, increase the size of the destination area or container to fit the component.
- Consider using responsive design techniques to adjust the component size based on the screen size or device.
