图书馆管理子系统需求分析: 1.借书过程:(1)学生到图书馆查询图书信息, (2)出示借书证, (3)办理借书。 2.还书过程:(1)判断是否超期、 (2)图书是否破损, (3)办理还书。按照要求给出正确的java具体代码不要伪代码

图书管理系统需求分析报告附有java代码JAVA语言
由于您并没有给出具体的要求和问题,我会根据您提供的需求分析,给出一个简单的借还书管理系统的Java代码示例:
```
import java.util.ArrayList;
public class LibrarySystem {
private ArrayList<Book> books;
private ArrayList<Student> students;
private ArrayList<BorrowRecord> borrowRecords;
public LibrarySystem() {
books = new ArrayList<Book>();
students = new ArrayList<Student>();
borrowRecords = new ArrayList<BorrowRecord>();
}
public void addBook(Book book) {
books.add(book);
}
public void addStudent(Student student) {
students.add(student);
}
public void borrowBook(Student student, Book book) {
if (!students.contains(student)) {
System.out.println("该学生不存在!");
return;
}
if (!books.contains(book)) {
System.out.println("该图书不存在!");
return;
}
if (book.isBorrowed()) {
System.out.println("该图书已被借出!");
return;
}
BorrowRecord record = new BorrowRecord(student, book);
borrowRecords.add(record);
book.setBorrowed(true);
System.out.println("借书成功!");
}
public void returnBook(Student student, Book book) {
if (!students.contains(student)) {
System.out.println("该学生不存在!");
return;
}
if (!books.contains(book)) {
System.out.println("该图书不存在!");
return;
}
boolean found = false;
for (BorrowRecord record : borrowRecords) {
if (record.getStudent().equals(student) && record.getBook().equals(book)) {
found = true;
borrowRecords.remove(record);
book.setBorrowed(false);
System.out.println("还书成功!");
break;
}
}
if (!found) {
System.out.println("该学生未借阅该图书!");
}
}
}
class Book {
private String name;
private String author;
private boolean isBorrowed;
public Book(String name, String author) {
this.name = name;
this.author = author;
isBorrowed = false;
}
public String getName() {
return name;
}
public String getAuthor() {
return author;
}
public boolean isBorrowed() {
return isBorrowed;
}
public void setBorrowed(boolean borrowed) {
isBorrowed = borrowed;
}
}
class Student {
private String name;
private String id;
public Student(String name, String id) {
this.name = name;
this.id = id;
}
public String getName() {
return name;
}
public String getId() {
return id;
}
@Override
public boolean equals(Object obj) {
if (obj instanceof Student) {
Student other = (Student) obj;
return id.equals(other.id);
}
return false;
}
}
class BorrowRecord {
private Student student;
private Book book;
public BorrowRecord(Student student, Book book) {
this.student = student;
this.book = book;
}
public Student getStudent() {
return student;
}
public Book getBook() {
return book;
}
}
```
这里定义了三个类:`LibrarySystem`、`Book`和`Student`,以及一个辅助类`BorrowRecord`。
其中,`LibrarySystem`代表整个图书馆管理系统,包含了所有的图书、学生和借阅记录。它提供了添加图书或学生、借书和还书等操作。
`Book`类代表一本图书,它包含了名称、作者和是否被借出的状态。
`Student`类代表一个学生,它包含了姓名和学号。
`BorrowRecord`类代表一条借阅记录,包含了借阅该图书的学生和图书本身。
上述代码只是一个简单的示例,实际的图书馆管理系统需要根据具体需求进行设计和实现。
