写一个学生信息管理系统 1.软件界面美观、功能完善软件，导航清晰，操作方便，使用菜单栏、工具栏、布局管理器、按钮、表格等多种Java图形界面组件。

好的，以下是一个简单的学生信息管理系统的Java代码示例，其中包含了对学生信息的添加、删除、修改和查询等功能，并且使用了Java Swing来构建用户界面：

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

public class StudentInfoApp extends JFrame {
    private JTable table;
    private DefaultTableModel model;
    private JTextField nameField;
    private JTextField idField;
    private JTextField ageField;
    private JTextField majorField;
    private JTextField searchField;

    private ArrayList<Student> students;

    public StudentInfoApp() {
        setTitle("学生信息管理系统");
        setSize(600, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        students = new ArrayList<Student>();

        // 创建菜单栏
        JMenuBar menuBar = new JMenuBar();
        JMenu fileMenu = new JMenu("文件");
        JMenuItem exitMenuItem = new JMenuItem("退出");
        exitMenuItem.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });
        fileMenu.add(exitMenuItem);
        menuBar.add(fileMenu);
        setJMenuBar(menuBar);

        // 创建工具栏
        JToolBar toolBar = new JToolBar();
        JButton addButton = new JButton(new ImageIcon("add.png"));
        addButton.setToolTipText("添加学生");
        addButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                addStudent();
            }
        });
        JButton deleteButton = new JButton(new ImageIcon("delete.png"));
        deleteButton.setToolTipText("删除学生");
        deleteButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                deleteStudent();
            }
        });
        JButton editButton = new JButton(new ImageIcon("edit.png"));
        editButton.setToolTipText("修改学生信息");
        editButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                editStudent();
            }
        });
        toolBar.add(addButton);
        toolBar.add(deleteButton);
        toolBar.add(editButton);
        add(toolBar, BorderLayout.NORTH);

        // 创建表格
        model = new DefaultTableModel();
        model.addColumn("姓名");
        model.addColumn("学号");
        model.addColumn("年龄");
        model.addColumn("专业");
        table = new JTable(model);
        table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
        table.setAutoCreateRowSorter(true);
        JScrollPane scrollPane = new JScrollPane(table);
        add(scrollPane, BorderLayout.CENTER);

        // 创建底部面板
        JPanel bottomPanel = new JPanel();
        bottomPanel.setLayout(new GridLayout(1, 2));
        JPanel searchPanel = new JPanel();
        JLabel searchLabel = new JLabel("搜索：");
        searchField = new JTextField(10);
        searchPanel.add(searchLabel);
        searchPanel.add(searchField);
        JButton searchButton = new JButton("搜索");
        searchButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                searchStudent();
            }
        });
        searchPanel.add(searchButton);
        bottomPanel.add(searchPanel);
        JPanel addPanel = new JPanel();
        addPanel.setLayout(new GridLayout(4, 2));
        JLabel nameLabel = new JLabel("姓名：");
        nameField = new JTextField(10);
        JLabel idLabel = new JLabel("学号：");
        idField = new JTextField(10);
        JLabel ageLabel = new JLabel("年龄：");
        ageField = new JTextField(10);
        JLabel majorLabel = new JLabel("专业：");
        majorField = new JTextField(10);
        addPanel.add(nameLabel);
        addPanel.add(nameField);
        addPanel.add(idLabel);
        addPanel.add(idField);
        addPanel.add(ageLabel);
        addPanel.add(ageField);
        addPanel.add(majorLabel);
        addPanel.add(majorField);
        bottomPanel.add(addPanel);
        add(bottomPanel, BorderLayout.SOUTH);

        setVisible(true);
    }

    // 添加学生信息
    private void addStudent() {
        String name = nameField.getText();
        String id = idField.getText();
        int age = Integer.parseInt(ageField.getText());
        String major = majorField.getText();
        Student student = new Student(name, id, age, major);
        students.add(student);
        model.addRow(new Object[] { name, id, age, major });
        clearInputFields();
    }

    // 删除学生信息
    private void deleteStudent() {
        int row = table.getSelectedRow();
        if (row != -1) {
            String id = (String) model.getValueAt(row, 1);
            for (int i = 0; i < students.size(); i++) {
                if (students.get(i).getId().equals(id)) {
                    students.remove(i);
                    break;
                }
            }
            model.removeRow(row);
        }
    }

    // 修改学生信息
    private void editStudent() {
        int row = table.getSelectedRow();
        if (row != -1) {
            String id = (String) model.getValueAt(row, 1);
            for (int i = 0; i < students.size(); i++) {
                if (students.get(i).getId().equals(id)) {
                    Student student = students.get(i);
                    student.setName(nameField.getText());
                    student.setAge(Integer.parseInt(ageField.getText()));
                    student.setMajor(majorField.getText());
                    model.setValueAt(student.getName(), row, 0);
                    model.setValueAt(student.getAge(), row, 2);
                    model.setValueAt(student.getMajor(), row, 3);
                    break;
                }
            }
            clearInputFields();
        }
    }

    // 搜索学生信息
    private void searchStudent() {
        String keyword = searchField.getText();
        if (!keyword.isEmpty()) {
            model.setRowCount(0);
            for (int i = 0; i < students.size(); i++) {
                Student student = students.get(i);
                if (student.getName().contains(keyword) || student.getId().contains(keyword)) {
                    model.addRow(new Object[] { student.getName(), student.getId(), student.getAge(), student.getMajor() });
                }
            }
        } else {
            refreshTable();
        }
    }

    // 清空输入框
    private void clearInputFields() {
        nameField.setText("");
        idField.setText("");
        ageField.setText("");
        majorField.setText("");
    }

    // 刷新表格
    private void refreshTable() {
        model.setRowCount(0);
        for (int i = 0; i < students.size(); i++) {
            Student student = students.get(i);
            model.addRow(new Object[] { student.getName(), student.getId(), student.getAge(), student.getMajor() });
        }
    }

    public static void main(String[] args) {
        StudentInfoApp app = new StudentInfoApp();
    }
}

该代码示例创建了一个名为“StudentInfoApp”的Java Swing窗口，其中包含了一个表格，用于显示学生信息，并提供了添加、删除、修改和查询等功能。同时，该代码示例还使用了菜单栏和工具栏来提高用户的使用体验。

希望这个示例代码可以为您提供一些参考和帮助，让您实现一个美观、功能完善的学生信息管理系统。
