java 用户界面设计 Student对象信息管理代码

以下是一个简单的Java用户界面设计示例，用于管理Student对象的信息：

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

public class StudentGUI extends JFrame implements ActionListener {
    private JTextField nameField, idField, majorField;
    private JButton addButton, removeButton, clearButton;
    private JTextArea displayArea;
    private StudentList studentList;

    public StudentGUI() {
        super("Student Information System");

        // 创建界面组件
        nameField = new JTextField(20);
        idField = new JTextField(20);
        majorField = new JTextField(20);
        addButton = new JButton("Add");
        removeButton = new JButton("Remove");
        clearButton = new JButton("Clear");
        displayArea = new JTextArea(10, 30);
        JScrollPane scrollPane = new JScrollPane(displayArea);

        // 将组件添加到界面
        JPanel inputPanel = new JPanel(new GridLayout(3, 2));
        inputPanel.add(new JLabel("Name:"));
        inputPanel.add(nameField);
        inputPanel.add(new JLabel("ID:"));
        inputPanel.add(idField);
        inputPanel.add(new JLabel("Major:"));
        inputPanel.add(majorField);

        JPanel buttonPanel = new JPanel();
        buttonPanel.add(addButton);
        buttonPanel.add(removeButton);
        buttonPanel.add(clearButton);

        JPanel displayPanel = new JPanel();
        displayPanel.add(scrollPane);

        Container contentPane = getContentPane();
        contentPane.setLayout(new BorderLayout());
        contentPane.add(inputPanel, BorderLayout.NORTH);
        contentPane.add(buttonPanel, BorderLayout.CENTER);
        contentPane.add(displayPanel, BorderLayout.SOUTH);

        // 添加事件监听器
        addButton.addActionListener(this);
        removeButton.addActionListener(this);
        clearButton.addActionListener(this);

        // 初始化StudentList对象
        studentList = new StudentList();

        // 设置界面属性
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
    }

    // 处理按钮事件
    public void actionPerformed(ActionEvent e) {
        String name = nameField.getText();
        String id = idField.getText();
        String major = majorField.getText();

        if (e.getSource() == addButton) {
            // 添加学生信息
            Student student = new Student(name, id, major);
            studentList.add(student);
            displayArea.append("Added: " + student + "\n");
        } else if (e.getSource() == removeButton) {
            // 移除学生信息
            Student student = new Student(name, id, major);
            if (studentList.remove(student)) {
                displayArea.append("Removed: " + student + "\n");
            } else {
                displayArea.append("Not found: " + student + "\n");
            }
        } else if (e.getSource() == clearButton) {
            // 清空显示区域
            displayArea.setText("");
        }
    }

    // Student类
    private 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;
        }

        public String toString() {
            return name + " (" + id + ", " + major + ")";
        }
    }

    // StudentList类
    private class StudentList {
        private java.util.List<Student> students;

        public StudentList() {
            students = new java.util.ArrayList<Student>();
        }

        public void add(Student student) {
            students.add(student);
        }

        public boolean remove(Student student) {
            return students.remove(student);
        }
    }

    // 测试代码
    public static void main(String[] args) {
        new StudentGUI();
    }
}

该程序包括一个StudentGUI类，该类继承自JFrame，并实现了ActionListener接口。它包括一个学生信息的输入面板，三个按钮（添加、删除和清空），以及一个学生信息的显示区域。在添加和删除学生信息时，程序将使用StudentList类来管理学生列表。
