利用Swing包中实现简单学生信息GUI

好的，我可以为你提供一个简单的Swing GUI程序，用来存储和显示学生的信息。下面是代码示例：

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

public class StudentGUI extends JFrame implements ActionListener {
    private JTextField nameField, idField, majorField;
    private JTextArea outputArea;
    private JButton addButton, displayButton;
    private ArrayList<Student> students;

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

        // 设置窗口属性
        setTitle("学生信息管理系统");
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // 创建组件
        nameField = new JTextField();
        idField = new JTextField();
        majorField = new JTextField();
        outputArea = new JTextArea();
        addButton = new JButton("添加学生");
        displayButton = new JButton("显示所有学生");

        // 添加组件
        JPanel inputPanel = new JPanel(new GridLayout(3, 2));
        inputPanel.add(new JLabel("姓名："));
        inputPanel.add(nameField);
        inputPanel.add(new JLabel("学号："));
        inputPanel.add(idField);
        inputPanel.add(new JLabel("专业："));
        inputPanel.add(majorField);

        JPanel buttonPanel = new JPanel(new GridLayout(1, 2));
        buttonPanel.add(addButton);
        buttonPanel.add(displayButton);

        JPanel mainPanel = new JPanel(new BorderLayout());
        mainPanel.add(inputPanel, BorderLayout.CENTER);
        mainPanel.add(buttonPanel, BorderLayout.SOUTH);
        mainPanel.add(new JScrollPane(outputArea), BorderLayout.EAST);

        add(mainPanel);

        // 监听按钮点击事件
        addButton.addActionListener(this);
        displayButton.addActionListener(this);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            // 添加学生
            String name = nameField.getText();
            String id = idField.getText();
            String major = majorField.getText();

            Student student = new Student(name, id, major);
            students.add(student);

            outputArea.append("添加学生：" + student.toString() + "\n");
        } else if (e.getSource() == displayButton) {
            // 显示所有学生
            outputArea.setText("");
            for (Student student : students) {
                outputArea.append(student.toString() + "\n");
            }
        }
    }

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

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

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

    @Override
    public String toString() {
        return "姓名：" + name + "，学号：" + id + "，专业：" + major;
    }
}

上面的程序创建了一个简单的学生信息管理系统GUI界面，包含三个输入框用于输入学生的姓名、学号和专业，添加学生和显示学生信息的按钮，以及一个文本区域用于显示添加的学生信息或者显示所有学生信息。你可以参考这个程序，自己编写一个类似的界面，来存储和显示学生的信息。
