JAVAswing老师管理系统源码

Java Swing是一个用于创建图形用户界面（GUI）的Java库。使用Java Swing可以开发出功能丰富、跨平台的桌面应用程序。下面是一个简单的Java Swing老师管理系统的源码示例，该系统可以实现基本的增删改查（CRUD）功能。

public class TeacherManagementSystem extends JFrame {

    private JTextField nameField, ageField, subjectField;
    private JButton addButton, updateButton, deleteButton, resetButton;

    private Teacher selectedTeacher;

    public TeacherManagementSystem() {
        setTitle("老师管理系统");

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setLayout(new BorderLayout());

        // 初始化表单
        JPanel formPanel = new JPanel(new GridLayout(4, 2));
        formPanel.add(new JLabel("姓名:"));
        nameField = new JTextField();
        formPanel.add(nameField);

            public void actionPerformed(ActionEvent e) {
                resetForm();
            }

        table.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                int selectedRow = table.getSelectedRow();
                if (selectedRow >= 0) {
                    selectedTeacher = teacherList.get(selectedRow);
                    nameField.setText(selectedTeacher.getName());

                }

    private void addTeacher() {
        String name = nameField.getText();
        int age = Integer.parseInt(ageField.getText());

            selectedTeacher.setName(nameField.getText());
            selectedTeacher.setAge(Integer.parseInt(ageField.getText()));

            tableModel.setValueAt(Integer.parseInt(ageField.getText()), selectedRow, 1);
            tableModel.setValueAt(subjectField.getText(), selectedRow, 2);
            resetForm();
        }
    }

    private void resetForm() {
        nameField.setText("");
        ageField.setText("");
        subjectField.setText("");
        selectedTeacher = null;
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new TeacherManagementSystem().setVisible(true);
            }
        });
    }
}

class Teacher {
    private String name;
    private int age;
    private String subject;

    public Teacher(String name, int age, String subject) {
        this.name = name;
        this.age = age;
        this.subject = subject;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getSubject() {
        return subject;
    }

    public void setSubject(String subject) {
        this.subject = subject;
    }
}

这个示例代码展示了如何使用Java Swing创建一个简单的老师管理系统，包括添加、删除、更新和重置功能。
