用java写一个学生管理系统要求可视化窗口

好的，我可以为您提供一个基本的Java学生管理系统的框架，它包括可视化窗口和基本的学生信息管理功能。您可以根据自己的需求进行修改和扩展。以下是代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.ArrayList;

public class StudentManagementSystem extends JFrame implements ActionListener {

    private JLabel nameLabel;
    private JLabel ageLabel;
    private JLabel genderLabel;
    private JLabel idLabel;

    private JTextField nameField;
    private JTextField ageField;
    private JTextField genderField;
    private JTextField idField;

    private JButton addButton;
    private JButton deleteButton;
    private JButton updateButton;
    private JButton searchButton;

    private JTable studentTable;
    private JScrollPane scrollPane;

    private ArrayList<Student> studentList;

    public StudentManagementSystem() {
        super("学生管理系统");
        setSize(800, 600);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // 初始化组件
        nameLabel = new JLabel("姓名：");
        ageLabel = new JLabel("年龄：");
        genderLabel = new JLabel("性别：");
        idLabel = new JLabel("学号：");

        nameField = new JTextField();
        ageField = new JTextField();
        genderField = new JTextField();
        idField = new JTextField();

        addButton = new JButton("添加");
        deleteButton = new JButton("删除");

        studentTable = new JTable();
        scrollPane = new JScrollPane(studentTable);

        // 添加组件到窗口
        JPanel inputPanel = new JPanel(new GridLayout(4, 2));
        inputPanel.add(nameLabel);
        inputPanel.add(nameField);
        inputPanel.add(ageLabel);
        inputPanel.add(ageField);

        inputPanel.add(idField);

        JPanel buttonPanel = new JPanel(new GridLayout(1, 4));
        buttonPanel.add(addButton);
        buttonPanel.add(deleteButton);
        buttonPanel.add(updateButton);
        buttonPanel.add(searchButton);

        JPanel tablePanel = new JPanel(new BorderLayout());
        tablePanel.add(scrollPane, BorderLayout.CENTER);

        JPanel mainPanel = new JPanel(new BorderLayout());
        mainPanel.add(inputPanel, BorderLayout.NORTH);
        mainPanel.add(buttonPanel, BorderLayout.CENTER);
        mainPanel.add(tablePanel, BorderLayout.SOUTH);

        add(mainPanel);

        // 添加事件监听器
        addButton.addActionListener(this);
        deleteButton.addActionListener(this);
        updateButton.addActionListener(this);
        searchButton.addActionListener(this);

        // 初始化学生列表
        studentList = new ArrayList<Student>();
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            // 添加学生
            String name = nameField.getText();
            int age = Integer.parseInt(ageField.getText());
            String gender = genderField.getText();
            String id = idField.getText();

            Student student = new Student(name, age, gender, id);
            studentList.add(student);

            updateTable();
        } else if (e.getSource() == deleteButton) {
            // 删除学生
            int row = studentTable.getSelectedRow();
            if (row >= 0) {
                studentList.remove(row);
                updateTable();
            }
        } else if (e.getSource() == updateButton) {
            // 修改学生
            int row = studentTable.getSelectedRow();
            if (row >= 0) {
                String name = nameField.getText();

                student.setName(name);
                student.setAge(age);
                student.setGender(gender);
                student.setId(id);

                updateTable();
            }
        } else if (e.getSource() == searchButton) {
            // 查找学生
            String id = idField.getText();
            for (int i = 0; i < studentList.size(); i++) {
                Student student = studentList.get(i);
                if (student.getId().equals(id)) {
                    studentTable.setRowSelectionInterval(i, i);
                    break;
                }
            }
        }
    }

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

        Object[] columnNames = {"姓名", "年龄", "性别", "学号"};
        studentTable.setModel(new DefaultTableModel(data, columnNames));
    }

    public static void main(String[] args) {
        StudentManagementSystem system = new StudentManagementSystem();
        system.setVisible(true);
    }
}

class Student {

    private String name;
    private int age;
    private String gender;
    private String id;

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

    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 getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
}

这个学生管理系统包含了添加、删除、修改和查找学生的功能，并且使用了可视化窗口和表格来展示学生信息。您可以根据自己的需求进行修改和扩展。
