使用JAVA做出简单的图形设计的学生信息管理系统的代码程序

以下是一个简单的基于JAVA Swing的学生信息管理系统的代码程序，仅供参考：

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new FlowLayout());

        nameLabel = new JLabel("Name:");
        add(nameLabel);
        nameField = new JTextField(10);
        add(nameField);

        idLabel = new JLabel("ID:");

            String gender = (String) genderBox.getSelectedItem();
            String major = majorField.getText();
            Student student = new Student(name, id, gender, major);

                Student student = new Student(name, id, gender, major);
                students.set(selectedRow, student);
                updateTable();
            }
        } else if (e.getSource() == searchButton) {
            String id = JOptionPane.showInputDialog(this, "Enter ID:");
            if (id != null && !id.isEmpty()) {
                for (int i = 0; i < students.size(); i++) {
                    if (students.get(i).getId().equals(id)) {
                        table.setRowSelectionInterval(i, i);
                        break;

            clearFields();
        }
    }

    private void updateTable() {
        Object[][] data = new Object[students.size()][4];
        for (int i = 0; i < students.size(); i++) {
            data[i][0] = students.get(i).getName();
            data[i][1] = students.get(i).getId();
            data[i][2] = students.get(i).getGender();
            data[i][3] = students.get(i).getMajor();
        }

    }

    private void clearFields() {
        nameField.setText("");
        idField.setText("");
        genderBox.setSelectedIndex(0);
        majorField.setText("");
    }

    public static void main(String[] args) {
        new StudentManagementSystem();
    }
}

class Student {
    private String name;
    private String id;
    private String gender;
    private String major;

    public Student(String name, String id, String gender, String major) {
        this.name = name;
        this.id = id;
        this.gender = gender;
        this.major = major;
    }

    public String getName() {
        return name;
    }

    public String getId() {
        return id;
    }

    public String getGender() {
        return gender;
    }

    public String getMajor() {
        return major;
    }
}

这个学生信息管理系统具有基本的添加、删除、更新、搜索和清除功能。当用户点击“Add”按钮时，程序将会使用四个文本框中的信息创建一个新的Student对象，并将其添加到ArrayList中。当用户选择一个表格行并点击“Delete”或“Update”按钮时，程序将会从ArrayList中删除或更新相应的Student对象。当用户点击“Search”按钮时，程序将会弹出一个对话框，要求用户输入ID以搜索相应的学生信息。当用户点击“Clear”按钮时，程序将会清除所有文本框中的内容。

请注意，这个程序只是一个简单的示例，它并没有对输入进行验证或错误处理，并且可以进一步改进和扩展。
