"INT型→WORD型转换-arm debug interface architecture specification adiv6.0 - 三菱微型可编程控制器 MELSECiQ-F FX5编程手册(指令/通用FUN/FB篇)" 这篇摘要涉及到的是编程中的一种数据类型转换操作,具体是INT型到WORD型的转换,这通常在嵌入式系统或PLC(可编程逻辑控制器)编程中出现。INT型和WORD型是两种常见的数据类型,INT通常表示16位的整数,而WORD在不同的上下文中可能代表16位或32位的整数,但在三菱MELSECiQ-F系列中,此处的WORD型应该是指16位数据。 转换函数名为INT_TO_WORD(_E),它接受一个INT类型的输入变量`s`,并将其转换为WORD类型的输出变量`d`。转换过程中,如果提供了EN/ENO功能,转换操作会受到控制。EN是一个执行条件,当其值为TRUE时,转换操作执行;如果EN为FALSE,转换停止。ENO是输出状态,如果转换成功,它的值为TRUE,否则为FALSE。如果在ENO为FALSE的情况下执行转换,输出`d`的数据将是不确定的,这时应避免使用`d`的值,需要进行适当的错误处理。 举例来说,如果INT型的`s`值为22136,转换后,WORD型的`d`值将为5678H(16进制表示)。这个转换过程在梯形图、FBD(功能块图)和LD(线束图)编程环境中都有对应的表示方式。 MELSECiQ-F系列是三菱推出的工业级可编程控制器,FX5是其中的一个型号,具备丰富的指令集和通用功能,适用于多种自动化应用。在使用前,用户需要熟悉相关手册,理解其功能和性能,确保安全操作。对于涉及人身安全的特殊用途,如原子能、电力、航空、医疗等领域,使用前需与制造商联系,确保产品的适用性和安全性。 手册中还强调了在使用产品时应注意的事项,包括产品不适用于直接关乎人身安全的系统,需要设置备用机制和安全功能,以及在遇到问题时寻求专业电气技术人员的帮助。手册内容可能随产品改进而更新,用户应保持关注并及时获取最新信息。如果发现书中内容有疑问或错误,应及时与制造商联系。

use java language ,In this project you need to write a book lending system for a Library. The system has different roles for registered users. There are two types of user roles: borrower and lender. Write an IUser interface for library users, with the following UML specification: +----------------------------------+ | <<interface>> | | IUser | +----------------------------------+ | + getName(): String | | + getBook(): int | | + moreBook(int number): void | +----------------------------------+ and a User class that implements IUser and has the following UML specification: +-----------------------------------+ | User | +-----------------------------------+ | - name: String | | - book: int | +-----------------------------------+ | + User(String name, int book) | | + getName(): String | | + getBook(): int | | # setBook(int book): void | | + moreBook(int number): void | | + testUser(): void | +-----------------------------------+ The name instance variable indicates the user name. The book instance variable indicates the number of books borrowed by the user. The setBook method changes the number of books borrowed by the user. The setBook method is protected, not public. This means that only subclasses of the User class can use the setBook method. All the other classes in the system cannot use the setBook method, so they cannot change the number of books borrowed by a user. The purpose of the moreBook method is to increase the number of books borrowed or lent by the user (depending on what kind of user it is) by the number given as argument to the method. The moreBook method of the User class is abstract, since we do not know what kind of role the user is (a borrower borrows books from other users and a lender lend books to other users). Also add to your program a Test class to test your User class. public class Test { public static void main(String[] args) { User.testUser(); } }
