用java写一个学生成绩管理系统要求可视化窗口

好的，我可以为你提供一个简单的学生成绩管理系统的Java代码，并使用Java Swing库实现可视化窗口。

首先，我们需要定义一个学生类，用于存储学生的信息和成绩。代码实现如下：

public class Student {
    private String name;
    private int mathScore;
    private int englishScore;
    private int programmingScore;

    public Student(String name, int mathScore, int englishScore, int programmingScore) {
        this.name = name;
        this.mathScore = mathScore;
        this.englishScore = englishScore;
        this.programmingScore = programmingScore;
    }

    public String getName() {
        return name;
    }

    public int getMathScore() {
        return mathScore;
    }

    public int getEnglishScore() {
        return englishScore;
    }

    public int getProgrammingScore() {
        return programmingScore;
    }
}

接下来，我们需要创建一个可视化窗口，用于展示学生信息和成绩。代码实现如下：

import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import java.awt.*;
import java.util.ArrayList;

public class StudentGradeManagementSystem extends JFrame {
    private ArrayList<Student> students;
    private JTable table;
    private DefaultTableModel model;
    private JTextField nameField;
    private JTextField mathField;
    private JTextField englishField;
    private JTextField programmingField;

    public StudentGradeManagementSystem() {
        students = new ArrayList<>();

        // 设置窗口标题和大小
        setTitle("学生成绩管理系统");
        setSize(600, 400);

        // 创建表格和表格模型
        table = new JTable();
        model = new DefaultTableModel(new Object[][]{}, new String[]{"姓名", "数学成绩", "英语成绩", "编程成绩"});
        table.setModel(model);

        // 创建添加学生信息的面板
        JPanel addPanel = new JPanel(new GridLayout(2, 4));
        JLabel nameLabel = new JLabel("姓名");
        JLabel mathLabel = new JLabel("数学成绩");
        JLabel englishLabel = new JLabel("英语成绩");
        JLabel programmingLabel = new JLabel("编程成绩");
        nameField = new JTextField();
        mathField = new JTextField();
        englishField = new JTextField();
        programmingField = new JTextField();
        JButton addButton = new JButton("添加");
        addButton.addActionListener(e -> addStudent());
        addPanel.add(nameLabel);
        addPanel.add(mathLabel);
        addPanel.add(englishLabel);
        addPanel.add(programmingLabel);
        addPanel.add(nameField);
        addPanel.add(mathField);
        addPanel.add(englishField);
        addPanel.add(programmingField);
        addPanel.add(addButton);

        // 将表格和添加学生信息的面板添加到窗口中
        add(new JScrollPane(table), BorderLayout.CENTER);
        add(addPanel, BorderLayout.SOUTH);

        // 显示窗口
        setVisible(true);
    }

    private void addStudent() {
        String name = nameField.getText();
        int mathScore = Integer.parseInt(mathField.getText());
        int englishScore = Integer.parseInt(englishField.getText());
        int programmingScore = Integer.parseInt(programmingField.getText());
        Student student = new Student(name, mathScore, englishScore, programmingScore);
        students.add(student);
        model.addRow(new Object[]{name, mathScore, englishScore, programmingScore});
        nameField.setText("");
        mathField.setText("");
        englishField.setText("");
        programmingField.setText("");
    }
}

最后，在main方法中创建StudentGradeManagementSystem对象，即可启动程序。

public class Main {
    public static void main(String[] args) {
        new StudentGradeManagementSystem();
    }
}

运行程序后，你将看到一个可视化的窗口，可以通过输入学生信息和成绩来添加学生，同时可以在表格中查看已添加的学生信息和成绩。
