Java图书管理系统项目代码

Java图书管理系统是一种功能强大的图书馆应用程序，可以帮助图书馆管理员管理图书
，包括添加，删除

，修改和查找图书。本文章将介绍一个基本的Java图书管理系统项目代码
，包括用户界面和图书馆管理功能。

首先，我们需要创建一个Java应用程序项目，可以使用Java Swing框架来创建用户界面
。以下是一个简单的代码示例
：

“`java
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class BookManager extends JPanel implements ActionListener {
private JTable booksTable;
private JTable authorTable;
private JTable subjectTable;

private int[] authorIds = new int[10];
private int[] subjectIds = new int[10];
private int[] titleIds = new int[10];
private int[] descriptionIds = new int[10];

public BookManager() {
booksTable = new JTable(data);
authorTable = new JTable(authorIds);
subjectTable = new JTable(subjectIds);
titleTable = new JTable(titleIds);
descriptionTable = new JTable(descriptionIds);
JPanel authorPanel = new JPanel();
authorPanel.setLayout(new GridLayout(3, 2));
authorTable.setRowHeaderColor(Color.BLACK);
authorPanel.add(authorTable.getRowHeader());
JPanel subjectPanel = new JPanel();
subjectPanel.setLayout(new GridLayout(3, 2));
subjectTable.setRowHeaderColor(Color.BLACK);

}
